Answer
estimated = 16
exact = 14$\frac{7}{16}$
Work Step by Step
4$\frac{1}{8}$ * 3$\frac{1}{2}$
Estimate the answer by rounding the mixed numbers
4$\frac{1}{8}$ round to 4 and 3$\frac{1}{2}$ round to 4
4 * 4 = 16
To find the exact answer, change each mixed number to an improper fraction.
4$\frac{1}{8}$ = $\frac{33}{8}$
3$\frac{1}{2}$ = $\frac{7}{2}$
Now multiply,
$\frac{33}{8}$ * $\frac{7}{2}$ = $\frac{231}{16}$ = 14$\frac{7}{16}$
The exact answer is 14$\frac{7}{16}$
The exact answer is reasonable.
