Question

Marissa dug three fifths of a hole in one tenth of an hour. Find the rate
in holes per hour

Answer 1

Explanation:

This might be easier to do in decimals. Let's try it.

3/5 = 0.6

1/10 = 0.1

rate = holes / hours

rate = 0.6/0.1

rate = 6 holes per hour

Try it with fractions.

rate =
`((3)/(5) )/((1)/(10) )` Invert and multiply the 1/10

rate =
`(3)/(5) *(10)/(1)` = 30/5 = 6

It's the same answer. Pick the method that you feel most comfortable with.
