Question

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

Answer 1

Answer:

24

Step-by-step 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

Answer:

24 -- if rounded off to provide whole number

Step-by-step explanation:

$13 \frac{7}{10} + 10\frac{1}{8}$

$\frac{137}{10} + \frac{81}{8}$

$\frac{8(137)}{80} +\frac{81(10)}{80}$   [ make the denominators same ]

$\frac{1096+810}{80}$            [ mix the fractions ]

$\frac{1906}{80}$                   [ addition ]

$\frac{953}{40}$                    [ simplify ]

$23\frac{33}{40}$ or 23.825
