Mr.Strand washed the most, and 7/20ths more laundry are left.

Step-by-step explanation:

In order to find what the larger amount actually is, we'll need to convert both the fractions into something comparable by using the same denominator. We can do this by multiplying 1/4 by 5/5 for the other denominator, and multiplying 2/5ths by 4/4. You'll then get 8/20, which is how much Mr.Strand washed, and 5/20, which is how much his son washed. We can conclude that since 8 is greater than 5, Mr. Strand washed the most. Now we add up both 8 and 5 to figure out how many things they washed together.  They washed 13 together, and the denominator is how much they need to wash total, we then subtract 13 from 20 to get 7. They need to wash 7 more things.

the answer is C 0.75 to 1.0
