Question

Estimate the quotient of $6899÷75$ by rounding off each number to its greatest place

Answer 1

$6899$ when rounded off to its thousands place is $7000$.

$75$ when rounded off to its tens place is $80$.

So, $7000÷80=\frac{7000}{80}$

$\begin{array}{rcl}& =& \frac{700}{8}\\ & =& \frac{696+4}{8}\\ & =& \frac{696}{8}+\frac{4}{8}\\ & =& 87+\frac{1}{2}\end{array}$

Hence, estimation of $6899÷75$ by rounding off each number to its greatest place is $87$.
