It makes 3/4 of an hour for an automated sprinkler to cover 2/7 of a lawn.After an hour has passed ,what fraction of a lawn has been covered

Answer 1

(3/4)/(2/7) = 1/x

(3/4)x = (2/7)

x = (2/7) / (3/4)

x = (2/7) * (4/3)

x = 8/21

Answer 2

This is just a way to convert hours to lawns

1 hr * (2/7 lawn)/(3/4 hr) = 2/7 * 4/3 = 8/21 lawn
