Exact
Multiply
$\frac{1}{2} \times \frac{1}{2}$ = $\frac{1}{4}$ tsp
(b) $\frac{3}{4} \times \frac{1}{2}$ cup
Estimate
Round fractions to the nearest whole number
$1 \times 1 = 1$ cup
Exact
Multiply
$\frac{3}{4} \times \frac{1}{2}$ = $\frac{3}{8}$ cup
(c) $1 \frac{3}{4} \times \frac{1}{2}$ cup
Estimate
Round fractions to the nearest whole number
$2 \times 1 = 2$ cups
Exact
Convert mixed numbers to improper fractions and multiply
$\frac{7}{4} \times \frac{1}{2}$ = $\frac{7}{8}$ cup
