Question

Kevin has a box of cereal that contains 10 1/2 cups . A serving size is 3/4 cup . How many servings in a box

Answer 1

Step 1. Convert the 10 1/2 cups to a fraction:

`10(1)/(2)=(10*2+1)/(2)=(20+1)/(2)=(21)/(2)`

10 1/2 cups is equal to 21/2 cups

Step 2. Divide the total of cereal in the box 21/2 by the cups per serving:

`(21)/(2)/(3)/(4)`

To make this division we follow the rule to divide fractions:

`(a)/(b)/(c)/(d)=(a* d)/(b* c)`

We apply this to our division:

`(21)/(2)/(3)/(4)=(21*4)/(2*3)`

solving the multiplications:

`(21)/(2)/(3)/(4)=(84)/(6)=14`

How many servings in a box​? Answer: 14
