Question

Ricky needs 3 1/4 cups of sugar to make muffins.he already has two and half cups.how many more cups of sugar does he need

Answer 1

Number of cups of sugar Ricky needs =  $3 \frac{1}{4} = \frac{13}{4}$

Number of cups of sugar Ricky already has =  $2 \frac{1}{2} = \frac{5}{2}$

Hence, number of cups of sugar Ricky requires = $\frac{13}{4} - \frac{5}{2} = \frac{13 -10}{4} = \frac{3}{4}$
