Answer 1

`x= 6(6)/(13)`

Explanation:

Given that for
`1(1)/(12)` =
`(13)/(12)` cup of sugar coretta recquire's 2 cups of flour

Now she has
`3(1)/(2)=(7)/(2)` cups of sugar

13/12 cups of sugar recquire 2 cups of flour

7/2 cups of sugar recquire x cups of flour

on cross multiplication we get

`(13x)/(12) =(2* 7)/(2)`

`x=(84)/(13)`

`x= 6(6)/(13)` cups of flour
