football cards and basketball cars respectively, follow the ratio 42:28
In order to simplify a ratio, or a fraction, or anything, you need to find the HCF (highest common factor) that goes into both 42 and 28. It must be a whole number, and must also equal a whole number. Once, you find this, divide it with the ration, respectfully.
Thus,
42 ÷ 7 = 4
28 ÷ 7 = 6
∴ simplified fraction is 4:6 

Hope this helps :)

Baseball cards : Football cards = 28 : 42

28 : 42

7 into 28 is 4 and 7 into 42 is 6

 28 : 42 = 4 : 6        

2 into 4 is 2 and 2 into 6 is 3

 28 : 42 = 4 : 6 = 2 : 3

So the simplified ratio of baseball cards to football cards is 2 : 3.

I  hope this helps.
