Question

Neil can put together 1/5 of his puzzle pieces in one hour what fraction of the puzzle will be solved after three hours

Answer 1

since the 1/5 represents the rate per hour you can just multiply by 3 to find the total

1/5 * 3 = 3/5

meaning that 3/5 of the puzzle will be complete after 3 hours

Answer 2

If he put together 1/5 of the puzzle in one hour the 3\5 of the puzzle should be complete in 3 hours. If he completes 1/5 of the puzzle every hour.
