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?

a
3 over 8 hour

b
1 over 2 hour

c
2 hours

d
4 hours

Answer 1

C-2 hours because if you multiply 1x4=4 1x8=8 and then you simplify by 4 and you got 2/1

Answer 2

C

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.
