Question

Estimate the answer by rounding each number to the nearest 10172+36.2+766.1+17.6

Answer 1

Given the expression :

`172+36.2+766.1+17.6​`

We will estimate the answer by rounding each number to the nearest 10

Look at the digit in the units place if 5 or greater add to the digit at the tens place

So,

`\begin{gathered} 172\approx170 \\ 36.2\approx40 \\ 766.1\approx770 \\ 17.6\approx20 \end{gathered}`

so, the answer will be :

`170+40+770+20=1000`

So, the answer is : 1,000
