Question

Use the properties and mental math to find the sum 8 1/5 + 3 2/5 + 5 4/5

Answer 1

Answer:

The answer is 17 2/5

Step-by-step explanation:

To find this, first add all the fractions together.

1/5 + 2/5 + 4/5 = 1 2/5

Now add all the whole numbers together.

8 + 3 + 5 = 16

Now add the two together.

16 + 1 2/5 = 17 2/5

Answer 2

$8\frac{1}{5} + 3\frac{2}{5} +5\frac{4}{5}$

$8 + 3 + 5 = 16 \\\frac{1}{5} + \frac{2}{5} +\frac{4}{5} = \frac{7}{5} = 1\frac{2}{5}$

16 + 1 = 17$\frac{2}{5}$

17.4
