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? (1 point)

4 hours

2 hours

3 over 8 hour

1 over 2 hour

Answer 1

It will take 2 hours

Answer 2

It would take 2 hours. To complete the whole lawn you would need:

`(8)/(8)`
To make a whole, so to get that we multiply:

`8 * (1)/(8) = (8)/(8)`
So we use the same number required for the whole lawn, and multiply it times the hours

`(1)/(4) * 8 = 2`
