Question

Estimate the product by rounding to the nearest hundred 712*763

Answer 1

In order to estimate the product by rounding to the nearest hundred,

first, we need to round the given factors to the required place value, in this case, hundred.

712 is rounded down to 700

763 is rounded up to 800

`\begin{gathered} 712\Rightarrow700 \\ 763\Rightarrow800 \end{gathered}`

Then, we multiply the rounded numbers

`700\cdot800=560,000`

the estimated product is 560,000

`712\cdot763\approx560,000`
