Question

Val walks 2 3/5 miles each day. Bill runs 10 miles once every 4 days. In 4days, who covers the greater distance.

Answer 1

The problem gives a distance with a fraction (not a decimal); there is absolutely no reason to convert it to a decimal. In 4 days, Val walks:     4*(2 3/5) miles     4*(13/5) miles           [convert to improper fraction]      52/5 miles       10 2/5 miles             [convert to mixed number] Compare that to Bill, who runs 10 miles every 4 days. Val runs a greater distance.
