Question

Brie completed 4/9 of her math problems after school. She completed 1/3 of her math problems in the evening. What fraction of her math problems are completed?

Answer 1

`(17)/(27)`

Step-by-step explanation

We have that she completed 4/9 of her math problems after school.

This means that the fraction of the problems left is:

1 - 4/9

= 5/9

She completed 1/3 of the remaining problems in the evening.

This means that she completed:

1 / 3 * 5 / 9

= 5/27

Therefore, the fraction of her math problems completed is therefore the sum of 4/9 and 5/27.

That is:

`\begin{gathered} (4)/(9)\text{ + }(5)/(27) \\ =\text{ }(17)/(27) \end{gathered}`

That is the fraction of the math problems completed.
