Answer 2

a)

1 % = 1/100

20 % = 20/100 = 10/50 = 5/25 = 1/5

80 % = 80/100 = 40/50 = 20/25 = 4/5

b)

15 % = 15/100 = 3/20

60 % = 60/100 = 30 /50 = 15/25= 3/5

75 % = 75/100 = 15/20 = 3/4

c)

120 % = 1 20/100 = 1 10/50 = 1 5/25 = 1 1/5

225 % = 2 25/100 = 2 1/4

350 % = 3 50 / 100 = 3 25/50 = 3 5/10 = 3 1/2
