Answer 1

SOLUTION

From the question, Tina bought

$\begin{gathered} 3\frac{1}{2}\text{ pounds of turkey and } \\ 2\frac{1}{4}\text{ pounds of ch}eese \end{gathered}$

But she used only

$1\frac{1}{2}\text{ pounds of ch}eese\text{ to make macaroni and ch}eese$

The amount of cheese she will have left is

$\begin{gathered} 2\frac{1}{4}-1\frac{1}{2} \\ \text{changing to improper fraction we have } \\ \frac{9}{4}-\frac{3}{2} \\ =\frac{9-6}{4} \\ =\frac{3}{4} \end{gathered}$

Hence she has

$\frac{3}{4}\text{ pounds of ch}eese\text{ left }$
