Question

Find the sum of -2 9/10 and -5 4/15. Then, in two or more complete sentences, explain the steps you used to add the mixed numbers.

Answer 1

Answer:

$\frac{-215}{30}$

Step-by-step explanation:

Given$-2\frac{9}{10} \ and\ -5\frac{4}{15}$

on solving this mixed fraction we get;

$-\frac{29}{10}\ and\ -\frac{64}{15}$

Now adding these fractions by same denominator method.

$-\frac{29\times3}{10\times3} +[-\frac{64\times2}{15\times2} ]\-\frac{87}{30} +[-\frac{128}{30}]\ = -\frac{215}{30}$

Answer 2

Answer:

-7 1/6

Step-by-step explanation:

The sum of -2 9/10 and -5 4/15 is -7 1/6. When we convert these fractions into improper fractions, they become -29/10 and -64/15. Now, we must make the denominator of each fraction equal to one another. Therefore, we must multiply -29/10 x 3 and -64/15 x 2 to get the denominator the same. The final answer is 215/30 which simplified is -7 1/6.
