Question

Alex and Freddy collect stamps. The ratio of the number of stamps in Alex's collection to the number in Freddy's collection is 3:5. How many more stamps does Freddy have if they have 136 stamps in all?

Answer 1

X=34

Explanation:

Add the given ratio

3+5=8

So Alex has 3 and Freddy has 5

So divide by the sum of the ratio

3/8×136=51 that is Alex own

Then 5/8×136=85 that is Freddy own

So 85-51=34

Answer 2

Answer: 34

Explanation:

1. The total parts of the ratio are 3 + 5 = 8

2. Each part is worth 136/8=17 stamps.

3. Freddy has 17x5=85 stamps.

4. Alex has 17x3=51 stamps

5. Freddy has 85 - 51 = 34 more stamps than Alex.
