Question

Chloe did some of her homework before dinner. She did 2/6 of her homework after dinner. She has 1/6 of her homework left. What fraction of her homework did Chloe do before her dinner? Write in simplest form.

Answer 1

She did 1/2 before dinner

Answer 2

If there are /6, then there are six parts of homework to do. If she has 1/6 homework left, that means she already did 5/6 of her homework. 5/6 - 2/6 she did after dinner is 3/6, or the amount of homework she did before dinner. Since three is half of six, we can simplify this expression to 1/2. 

So the correct answer would be that Chloe did 1/2 of her homework before dinner.
