So, if 60 beats was decreased by 2/5 before, we know that 60 beats = 3/5 of her heart rate after she ran the mile.
(Because 1 - 2/5 = 3/5)
So, 3/5 = 60, and we're trying to find 1.
So I would first divide both sides by 3.
3/5 = 60
/3 /3
1/5 = 20
Then multiply both sides by 5.
1/5 * 5 = 20 * 5
1 = 100
So her heart rate was 100 beats per minute immediately after she ran the mile.
