Angelina is painting her room. She wants a very specific shade of bright blue paint, so she mixes blue and green paint in a ratio of 2:1 . If she needs 6 gallons of paint, how many gallons of blue paint should she buy? Use a tape diagram to help organize your thinking.(1 point)
gallons
To find out how many gallons of blue paint Angelina should buy, we need to determine the ratio of blue paint to the total amount of paint she needs.
The ratio given is 2:1, which means for every 2 parts of blue paint, there is 1 part of green paint.
Let's represent the total amount of paint needed (6 gallons) using a tape diagram:
[|______:______|______:______|______:______|______:______|______:______|______:______|]
Since the ratio is 2:1, we can divide the tape diagram into 3 parts (2 parts blue paint and 1 part green paint):
[|______:______|______:______|______:______|]
Each part represents 2 gallons.
Therefore, Angelina should buy 2 x 2 = 4 gallons of blue paint.
Breanna plays on her middle school basketball team. For every 5 shots she takes, she makes 2 baskets. If she makes 8 baskets, how many shots did she take? Use a tape diagram to help organize your thinking.(1 point)
shots
Skip to navigation
To find out how many shots Breanna took, we need to determine the ratio of shots to baskets.
The ratio given is 5:2, which means for every 5 shots she takes, she makes 2 baskets.
Let's represent the total number of shots using a tape diagram:
[|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|]
Since the ratio is 5:2, we can divide the tape diagram into groups of 5 and 2:
[|______:______|______:______|______:______|______:______|______:______|]
Each group represents 5 shots.
Since Breanna made 8 baskets, we need to find out how many groups of 5 shots make a total of 8 baskets.
8 ÷ 2 = 4
Therefore, Breanna took 4 x 5 = 20 shots.
Question
A new superhero movie has its first showing and there are 155 people in line to see it. If the ratio of kids to adults waiting to see this movie is 3:2 , how many adults are in line? Use a tape diagram to help organize your thinking.(1 point)
adults
To find out how many adults are in line, we need to determine the ratio of kids to adults.
The ratio given is 3:2, which means for every 3 kids, there are 2 adults.
Let's represent the total number of people in line using a tape diagram:
[|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|______:______|

Since the ratio is 3:2, we can divide the tape diagram into groups of 3 and 2:
[|______:______|______:______|______:______|]
Each group represents 3 kids and 2 adults.
To find out how many groups of 2 adults make a total of 155 people, we divide:
155 ÷ 2 = 77.5
Since we can't have half a group, we round down to the nearest whole number.
Therefore
