Answer 2

Given,

2. 56723+ 4567 + 72 + 5

3.9656724 + 8567

4.160756 + 2562 + 72

To find,

The sum

Solution,

1) 2. 56723+ 4567 + 72 + 5 = 4,646.56723

Round off = 4646.56

= 4647

= 4650 (nearest 10s)

2) 3.9656724 + 8567 = 8,570.9656724

Round off = 8570.96

= 8571

= 8570 (nearest 10s)

3) 4.160756 + 2562 + 72 = 2,638.160756

Round off = 2638.16

= 2638

= 2640 (nearest 10s)
