The nutritional chart on the side of a box of a cereal states that there are 116 calories in a 1 and one third
cup serving. How many calories are in 6 cups of the cereal?
**Practice problem I can get help on. I have a test on this soon*
1 1/3 cups -----> 116 calories
or
4/3 cups ------> 116 calories
1 cups ------> 116(3/4) calories
then 6 cups -----> ??? calories
116cal./(1 1/3cup) = 116/(4/3) = 87 cal./cup.
87cal./cup * 6cups = __ calories.
To find the number of calories in 6 cups of cereal, we can use a basic proportion.
1 1/3 cups of cereal has 116 calories.
First, we need to find out how many calories are in 1 cup of cereal. To do this, we divide 116 calories by 1 1/3 cups.
116 calories ÷ 1 1/3 cups
Since 1 1/3 is equal to 4/3, we rewrite the division problem as:
116 calories ÷ (4/3) cups
To divide by a fraction, we can multiply by its reciprocal (flip the fraction):
116 calories x (3/4) cups
Multiplying across:
348 calories ÷ 4 cups
86.25 calories per cup
Now, we have determined that there are 86.25 calories in 1 cup of cereal.
To find the number of calories in 6 cups of cereal, we multiply 86.25 calories by 6:
86.25 calories x 6 cups = 517.5 calories
Therefore, there are 517.5 calories in 6 cups of the cereal.
