Domino · Answer 1

All number in percentage form when converted into a fraction will serve as the numerator with 100 as the denominator. The percent sign will be removed and the fraction will be simplified.

42% = 42/100 = (42:2) / (100:2) = 21/50

72% = 72/100 = (72:2) / (100:2) = 36/50 = (36:2) / (50:2) = 18/25

88% = 88/100 = (88:2) / (100:2) = 44/50 = (44:2) / (50:2) = 22/25

35% = 35/100 = (35:5) / (100:5) = 7/20

Notice that both numerator and denominator must be factored by the same number to be simplified.

Put each one over 100. So 42/100, then reduce down by dividing by 2 both the top and bottom figures and you get 21/50 for your first answer. Do the same with each of the rest ... 72/100 and reduce down to 36/50, then reduce again 18/25 and that is the farthest you can reduce on that one. Do the same for the rest.
