Alex and freddy collect stamps. the number of stamps in alex’s collection to the number of stamps in freddy’s collection is in the ratio of 3: 5. how much more stamps does freddy have if together they have 136 stamps? explain how you got the answer.

Remark

The trick here is to realize that you have to find the number both have in order to find the difference. That means you take (effectively) 3/8 and 5/8 to find out how much each of them has. The 8 stands for the 136

Step One

Find the number of stamps Alex has. Remember his ratio is the smaller so he will have 3/8

Alex = 3/8 * 136

Alex = 408/8 = 51

Step 2

Find the number that Freddy has.

The total is 136

Formula

Freddy = Total - Alex

Freddy = 136 - 51

Freddy = 85

Check

Let us see if 5/8 * 136 = 85

5*136/8 = 680 / 8 = 85 So your answers are correct.

Difference

Difference = 85 - 51 = 34 which is how many more stamps Freddy has than Alex.

360/29
