Round 73,486 to the nearest ten. ANS. Blank 1. Fill in the blank, read surrounding text.

Answer 1

SOLUTION

Concept: Rounding-off of Numbers

To round off numbers, you follow the rule below

$\begin{gathered} 0-4=\text{round off to 0 and add to the previous digit} \\ 5-9=\text{round off to 1 and add to the previous digit} \end{gathered}$

To round off the number to the nearest tens

$73,486$

Identify the tens digit, which is

$8$

The number before it is

$\begin{gathered} 6\text{ } \\ \text{which is rounded off to 1 and added to the tens digit } \end{gathered}$

Then the value becomes

$73,490$

Therefore 73,486 becomes 73,490 to the nearest ten
