Question

Estimate each of the following using general rule:

(a) $730+998$

Answer 1

Use concept of estimation:

Given that, $730+998$

On rounding off the numbers to hundreds we get

$730$ rounds off to $700$

$998$ rounds off to $1000$

So, $730+998$ is estimated to

$$\begin{gathered} 700+1000 \\ =1700 \end{gathered}$$

Hence, $730+998$ is estimated to $1700$
