Answer
Estimate: 16$\div$3= $5\frac{1}{3}$
Exact : $5\frac{1}{6}$
Work Step by Step
$15\frac{1}{2}\div3$
= $15\frac{1}{2}\div\frac{3}{1}$
First we need to find Estimate:
$15\frac{1}{2}$ rounded to 16
$\frac{3}{1}$ rounded to 3
16$\div$3= $5\frac{1}{3}$(Estimate)
Now we need to find Exact:
$15\frac{1}{2}\div3$
= $\frac{31}{2}\div\frac{3}{1}$
= $\frac{31}{2}\times\frac{1}{3}$
= $\frac{31\times1}{2\times3}$
= $\frac{31}{6}$
= $5\frac{1}{6}$
