Question

PLEASE HELP!!! I DON’T KNOW THISSS

Jenny has only 3 1/2 cups of flour in her house. She needs 1 5/8 cups for a brownie recipe. Her sister Jody needs 1 3/4 cup flour for her cookie recipe. Will there be enough flour for both recipes?

Answer 1

`YES.`

Explanation:

`if \: 1 (5)/(8) + 1 (3)/(4) = 3.375 \\ and \\ 3 (1)/(2) = \: 3.5 \\ then \: 3.5 > 3.375`

Answer 2

yes, she will still have 1/8 of a cup left

Explanation:

you have to convert all the fractions to have the same denominator.

to do that you need improper fractions

3 1/2= 7/2

1 5/8= 13/8

1 3/4= 7/4

with this information, you need to find a common number between 2, 8, and 4. the largest number that they all fit into is 8.

so 7/2 becomes 28/8

13/8 stays the same

and 7/4 becomes 14/8

add 13/8 and 14/8 and subtract from 28/8

you get 1/8, which means you have enough flower for both recipes!
