Question

Estimate the answer by rounding each fraction to the nearest whole number and then adding.

13 7/10
+
10 1/8

Answer 1

24

Explanation:

First, we round the fractions.

If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.

7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.

1/8 is less than half so we round down and remove the fraction so we are left with 10.

Then we add.

14+10=24

Answer 2

24 -- if rounded off to provide whole number

Explanation:

`13 (7)/(10) + 10(1)/(8)`

`(137)/(10) + (81)/(8)`

`(8(137))/(80) +(81(10))/(80)` [ make the denominators same ]

`(1096+810)/(80)` [ mix the fractions ]

`(1906)/(80)` [ addition ]

`(953)/(40)` [ simplify ]

`23(33)/(40)` or 23.825
