Crayola Classic markers come in packages of eight. Crayola Tropical markers come in packages of ten. Sheldon wants the same number of Classic and Tropical markers. What is the fewest number of packages he could buy of each type of marker? Show proof of your answer.

Crayola Classic: 5 Packs; Crayola Tropical: 4 Packs

Step-by-step explanation:

Keep multiplying by both until you get a number equal to eachother

1. 8 x 2 = 16,  10 x 2 = 20

2. 8 x 3 = 24, 10 x 3 = 30

You may notice that the numbers are getting farther apart. This is normal because the boxes are not equal and are getting multiplied further. That means that your answer will have different factors in both the equations.

3. 8 x 4 = 32, 10 x 4 = 40

4. 8 x 5 = 40

Both of those equations (in bold) have the same answer and he wanted the same crayons from both. So, the answer is:

10 x 4 = 40

8 x 5 = 40

(how much packs of each you need to get the same amount)

Hope this helps :)
