Answer:

7/20 still needs to be washed.

Step-by-step explanation:

You will need to find the lowest common multiple and add the two fractions together and subtract that sum from 1. The 1 represents the total amount of laundry and the sum you will find represents the fraction of laundry that Mrs. Rios and her son have already washed combined.    

1/4 + 2/5

= 5/20 + 8/20

= 13/20

1 - 13/20

= 20/20 - 13/20

= 7/20
