Question

If a sprinkler waters 1 over 8 of a lawn in 1 over 4 hour, how much time will it take to water the entire lawn?

Answer 1

1/8 of the lawn in 1/4 of an hour. That mean you would need a whole hour to do 4/8 or 1/2 of the lawn. So you would need two hours to do the whole lawn. 

Answer 2

Its two hours because 1/4 of an hour is 15 Minute so in 2 hours you have 8/8 because every 1/4 hour it's 1/8 and there are 4  1/4 in a hour
