Question

Estimate each sum to the nearest ten
1. (57+34)​

Answer 1

Answer:

Here we have to do the estimation of the sum of (57+34)

to the nearest ten. To estimate this, first of all we look at the one’s place of both the terms under addition. If the number is greater than or equal to 5

replace it with 10

and if the number is less than 5

replace it with 0

. Then just add those new numbers, you will get the required estimate at the nearest ten.

Complete step-by-step answer:

To estimate (57+34)

to the nearest ten, we see the individual digits or numbers at one’s place. If the digit/number is <5

, it is converted to zero and if it is ⩾5

, then it is converted to 10

.

Here, we have numbers 57

and 34

. When we look at 34

we see that the number in one's place is 4

. Now, since 4<5

so we replace 4

with 0

and hence 34

with 30

.

When we look at 57

see that number in one's place is 7

. Now, since 7>5

so we replace 7

with 10

and hence 57

with 60

.

Hence we do the sum as (60+30)=90

.

So, the estimated value of the sum of (57+34)

to the nearest ten is 90.!
