Estimate 25.65 + 13.23 + 6.35 by rounding each number to the nearest tenth.
26 +13 + 6 = 45
25.7 + 13.3 + 6.4 = 45.4
25.6 + 13.2 + 6.3 = 45.1
25.7 + 13.2 + 6.4 = 45.3

Answer 1

`25.7 + 13.2 + 6.4 = 45.3`

Explanation:

Given

`Expression: 25.65 + 13.23 + 6.35`

Required

Approximate to nearest tenth and solve

Approximating each term to the nearest tenth, we have

`25.65 = 25.7`

`13.23 = 13.2`

`6.35 = 6.4`

Bring the approximated term together:

`Expression: 25.65 + 13.23 + 6.35` becomes

`Expression: 25.7 + 13.2 + 6.4`

`25.7 + 13.2 + 6.4 = 45.3`

Hence:
