#### Answer

Approximately 75 New Hampshire supermarkets are in shopping centers. 61 supermarkets are in shopping centers.

#### Work Step by Step

Use front end rounding to estimate the number of supermarkets in New Hampshire. $163 \approx 200$ Multiply by $\frac{3}{8}$ to find the number that are in shopping centers. $200 \times \frac{3}{8}$ = $\frac{200}{1} \times \frac{3}{8}$ = $\frac{600}{8}$ = $\frac{600 \div 8}{8 \div 8}$ = $\frac{75}{1}$ = 75 To find the exact number that are in shopping centers multiply the exact number of New Hampshire supermarkets by $\frac{3}{8}$. $163 \times \frac{3}{8}$ = $\frac{163}{1} \times \frac{3}{8}$ = $\frac{489}{8}$ = $\frac{489 \div 8}{8 \div 8}$ = $\frac{61R1}{1}$ = $61 \frac{1}{8}$ $\approx 61$
