The two fractions that we can extract from the given rates above are:
(1) 12 pages / 20 minutes
(2) 20 pages / 32 minutes
We can reduce the fractions or rates to their lowest term by dividing the numbers by 4 such that,
(1) 3 pages / 5 minutes
(2) 5 pages / 8 minutes
Therefore, the rates are not equivalent.
