Aaron had 3/4 as many badges as Ben. Ben has 2/5 as many badges as Calvin. Aaron has 8 badges fewer than Ben. How many more badges does Calvin have than Ben?

3 : 4

Ben : Calvin

2 : 5

4 : 10

Aaron : Ben : Calvin

3 : 4 : 10

4 - 3 = 1

1u ------- 8

4u ------- 8 x 4 = 32 (Ben)

10u ------- 8 x 10 = 80 (Calvin)

80 - 32 = 48

OR

10 - 4 = 6

6u ------- 6 x 8 = 48

Ans : 48 more badges.
