Call the number you are looking for N
So we konw 15% of is 60 so we write
.15N=60
Now to find N divide both sides by .15
N=60/.15=400
So check it without a calculator, note that 10% of 400 is 40 and half of that is 20 so that is 5% of 400. Now 40+20=60 as desired

Divide the number of minuets by 60 (number of mins in an hour) and multiply by 100 to get into a percentage. e.g. 15 mins as a percentage of an hour: (15 / 60) * 100 = 25 % (15/60 = 1/4 or 0.25) 28 mins as a percentage of an hour: (28 / 60) * 100 = 47 % (to nearest whole percent) (28/60 = 0.46666667 (t8dp))
15/25 x 100 = 60 percent
