Mr. Abbot washed 1/4 of his laundry. His son washed 2/5 of it. Who washed most of the laundry? How much of the laundry still needs to be washed?

Mr. Abbot washed 25% and his son washed 40% so his son washed more and 35% of it still needs to be washed

Step-by-step explanation:

7/20 of it still needs to be washed if you need it in a fraction.

35% of the laundry still needs to be done

1/4 of the laundry equates to 25%

and 2/5 equal 40%

when combined, they equal 65%

and when 65 is subtracted from 100. 35% remains to be done. 35% also equals 7/20

your answer is option c.
