of it. Who washed most of the laundry? How much of the laundry still needs to be washed?

Answer 1

1/3 (washed by son) - 2/7 (washed by Mrs. Larson) = 1/21 of the laundry is left to be washed.Now, we know that 1/21 of the laundry is left to be washed. However, we don't have enough information to determine who washed more of the laundry
