Answer
Estimate: $18$
Exact: $12$
Work Step by Step
Estimate: round the three numbers to 3, 2, and 3 and multiply.
Exact: change the numbers into improper fractions: $\frac{3}{1}, \frac{3}{2}, \frac{8}{3}$
Multiply: $\frac{3}{1}\times\frac{3}{2} = \frac{9}{2}$
$\frac{9}{2}\times\frac{8}{3} = \frac{12}{1}$
Change into a mixed (or whole) number: $12$
