Answer 2

Given,

Expression:

734 + 998.

To find,

Estimate the expression by rounding off the nearest tens.

Solution,

To round off a given number to the nearest tens, the rules given below need to be followed.

1. If the unit digit of the number is less than 5 (< 5), the unit digit is simply replaced by 0.
2. Secondly, if the unit digit is equal to or more than 5, but less than 10, (that is from 5 to 9), 1 is added to the tens digit, and the unit digit is replaced by 0.

The given expression is,

734 + 998

Using the above rules, we can see that,

734, on rounding off to nearest 10s will be = 730, and

998, on rounding off to the nearest 10s will be = 1000.

Thus,

734 + 998

= 730 + 1000

= 1730.

Therefore, the expression 734 + 998, by rounding off the nearest tens will be estimated as 1730.
