Answer 1

Answer:

$x= 6\frac{6}{13}$

Step-by-step explanation:

Given that for $1\frac{1}{12}$ = $\frac{13}{12}$ cup of sugar coretta recquire's 2 cups of flour

Now she has $3\frac{1}{2}=\frac{7}{2}$ 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

$\frac{13x}{12} =\frac{2\times 7}{2}$

$x=\frac{84}{13}$

$x= 6\frac{6}{13}$ cups of flour
