Answer
(a) Estimate 4 cups
Exact $2 \frac{5}{8}$ cups
(b) Estimate 2 cups
Exact $1 \frac{1}{8}$ cups
(c) Estimate 0 cups
Exact $ \frac{1}{2}$ cup
Work Step by Step
(a) $1 \frac{3}{4} \times 1 \frac{1}{2}$ cups
Estimate
Round fractions to the nearest whole number
$2 \times 2 = 4$ cups
Exact
Convert mixed numbers to improper fractions and multiply
$\frac{7}{4} \times \frac{3}{2}$ = $\frac{21}{8}$
Convert improper fractions to mixed numbers
$\frac{21}{8}$ = $2 \frac{5}{8}$ cups
(b) $\frac{3}{4} \times 1 \frac{1}{2}$ cups
Estimate
Round fractions to the nearest whole number
$1 \times 2 = 2$ cups
Exact
Convert mixed numbers to improper fractions and multiply
$\frac{3}{4} \times \frac{3}{2}$ = $\frac{9}{8}$
Convert improper fractions to mixed numbers
$\frac{9}{8}$ = $1 \frac{1}{8}$ cups
(c) $\frac{1}{3} \times 1 \frac{1}{2}$ cups
Estimate
Round fractions to the nearest whole number
$0 \times 2 = 0$ cups
Exact
Convert mixed numbers to improper fractions and multiply
$\frac{1}{3} \times \frac{3}{2}$ = $\frac{3}{6}$
Reduce the fraction
$\frac{3}{6}$ = $\frac{1}{2}$ cup
