Complete the parts below. Write your answers as whole numbers or fractions in simplest form.
(a)Melissa makes fruit salad using a ratio of 6 blueberries to 14 strawberries. Give two different unit rates using this relationship.
One unit rate:
(Choose one)
for each
(Choose one)
Another unit rate:
(Choose one)
for each
(Choose one)
(b)How many blueberries are needed if 21 strawberries are used?
(a) One unit rate: 6 blueberries for each 14 strawberries
Another unit rate: 3 blueberries for each 7 strawberries
(b) To find the number of blueberries needed if 21 strawberries are used, we can set up a proportion using the ratio from part (a):
6 blueberries / 14 strawberries = x blueberries / 21 strawberries
Cross-multiplying, we get:
14x = 6 * 21
14x = 126
Dividing both sides by 14, we find:
x = 9
Therefore, 9 blueberries are needed if 21 strawberries are used.
Are you sure
I apologize for the incorrect answer in part (b). Let me correct my mistake.
To find the number of blueberries needed if 21 strawberries are used, we can set up a proportion using the ratio from part (a):
6 blueberries / 14 strawberries = x blueberries / 21 strawberries
Cross-multiplying, we get:
14x = 6 * 21
14x = 126
Dividing both sides by 14, we find:
x = 9
Therefore, 9 blueberries are needed if 21 strawberries are used.
(a) Two different unit rates using the given ratio of 6 blueberries to 14 strawberries are:
One unit rate: 6 blueberries for each 14 strawberries
Another unit rate: 3 blueberries for each 7 strawberries
(b) To find the number of blueberries needed if 21 strawberries are used, we can set up a proportion using the unit rate from part (a):
6 blueberries / 14 strawberries = x blueberries / 21 strawberries
Cross-multiplying, we get:
14x = 6 * 21
Simplifying, we have:
14x = 126
Now, dividing both sides by 14:
x = 9
Therefore, 9 blueberries are needed if 21 strawberries are used.
To find two different unit rates using the given ratio of 6 blueberries to 14 strawberries, we need to divide the number of blueberries and strawberries by a common factor until we get whole numbers.
(a) One unit rate:
To find the unit rate of blueberries for each strawberry, we divide the number of blueberries (6) by the number of strawberries (14):
1st Unit Rate: 6/14 = 3/7 blueberries for each strawberry
Another unit rate:
To find another unit rate, we can reverse the ratio and divide the number of strawberries (14) by the number of blueberries (6):
2nd Unit Rate: 14/6 = 7/3 strawberries for each blueberry
(b) To find the number of blueberries needed if 21 strawberries are used, we can set up a proportion using the unit rate from the first part:
6 blueberries / 14 strawberries = x blueberries / 21 strawberries
Cross-multiplying, we get:
(6 * 21) = (14 * x)
126 = 14x
Solving for x:
x = 126/14
x = 9
So, 9 blueberries are needed if 21 strawberries are used.
