1) To classify let's calculate.
20% of 150 = 0.2 x 150 =30
60% of 50 = 0.6 x 50 = 30
25% of 80 = 0.25 x 80 = 20
12% of 250 = 0.12 x 250 = 30
10% of 200 =0.1 x 200 = 20
50% of 40 = 0.5 x 40 = 20
2) Now that we know how much each percentage represents let's classify them:
Categories of 20 | Categories of 30
25% of 80 20% of 150
10% of 200 60% of 50
50% of 40 12% of 250
On the left, each percentage is equivalent to 20.
On the right, each one is equivalent to 30
