Question

Isaiah mows a lawn in 3 hours. What unit fraction would be used to convert this to the number of minutes it takes him to mow a lawn?

A.) 1 hour / 60 minutes

B.) 3 hours / 60 minutes

C.) 60 minutes / 1 hour

Answer 1

Hey there.. your answer is A. Since 1 hour equals 60 minutes, by elimination you would use either 60 minutes/1 hour or 1 hour/60 minutes. The ratio would have hours on top, so by further elimination you would use 1 hour/60 minutes. The ratio would be: $\frac{3hours}{x}$ = $\frac{1hour}{60minutes}$
