Answer
Estimate = 6
Exact = $6\frac{7}{8}$
Work Step by Step
$5\frac{1}{2}.1\frac{1}{4}$
First we need to find Estimate:
$5\frac{1}{2}$ rounded to 6
$1\frac{1}{4}$ rounded to 1
6$\times$1=6 (Estimate)
Now we need to find Exact:
$5\frac{1}{2}.1\frac{1}{4}$
= $\frac{11}{2}\times\frac{5}{4}$
= $\frac{11\times5}{2\times4}$
= $\frac{55}{8}$
= $6\frac{7}{8}$
