Question

There was 3/5 of a gallon of paint in the bucket. Dr. Wu used 2/5 of that. How much paint was left?

Answer 1

1/5

Explanation:

equation: 3/5-2/5=x

we can multiply the whole equation by 5 so that we can easily subtract the numbers

3-2=1

now we divide it by 5 so that we get our number in a fraction

after we divide we get 1/5
