Question

Joe has 5/6 cup of paint in a container. He uses 2/5 cup on a project then adds another 1/3 cup. How much paint does he have now?

Answer 1

=23/30

Explanation:

5/6-2/5

Multiply 5/6 by 5 and -2/5 by 6

25/30-12/30

25-12/30

=13/30

Then he adds another 1/3

=13/30+1/3

multiply 1/3 by ten

=13/10 + 10/30

=13+10/30

=23/30

5/6-2/5-1/3=23/30
