Question

Estimate the following product :$958\times 387$

Answer 1

Given product is $958\times 387$

For rounding off to nearest hundreds,we first check the digit at ten's place.If the digit at ten's place is less than $5$ then we replace its ten's and one's place by zero but if the digit at ten's place is $\ge 5$ then we add $1$ to hundred's place digit and then replace ten's place and one's place by zero.

$\begin{array}{rcl}958& \to & 1000(nearesthundreds)\\ 387& \to & 400(nearesthundreds)\\ So,958\times 387& =& 1000\times 400\\ & =& 400000\end{array}$

Hence, Estimation of the following product :$958\times 387$ is $400000$.
