Solving proportions problem

Question

If I am painting at a constant rate and I use 2/3 can of paint in 1 1/2 hour. What fraction of a can of paint will I use in 1 hour?

Answer 1

1 is 2/3 of 1 1/2

2/3 of 2/3 =4/9 of a can will be used in 1 hour

4/9 in one hour 2/9 in half an hour

4/9 + 2/9 + 6/9 = 2/3 in 1 1/2 hour
