Dinah spends 1/5 of her homework time on math and 2/3 of it on writing. What fraction of her homework time is spent on math and writing? Simplify the answer if possible.

1 answer

To add these two fractions, we need to find a common denominator. The least common multiple of 5 and 3 is 15.

Dinah spends 1/5 of her homework time on math, which is equal to 3/15.

Dinah spends 2/3 of her homework time on writing, which is equal to 10/15.

To find the total fraction of her homework time spent on math and writing, we can add these two:

3/15 + 10/15 = 13/15

Therefore, Dinah spends 13/15 of her homework time on math and writing.
