Given: The ratio of jars of jelly to jars of peanut butter = 5 : 6
From this information, there are infinitely-many possibilities.
Here are a few of those possibilities:
There are 5 jars of jelly and 6 jars of peanut butter
There are 10 jars of jelly and 12 jars of peanut butter
There are 15 jars of jelly and 18 jars of peanut butter
There are 20 jars of jelly and 24 jars of peanut butter
There are 25 jars of jelly and 30 jars of peanut butter
.
.
.
etc
Notice that the number of jars of peanut butter it's always a multiple of 6
So the correct answer(s) must be multiples of 6
Check the answer choices.... C and D are the only multiples of 6
Answer: C, D
