Question

Morgan and Kira have a number of jelly beans in a ratio of 5 : 3. Kira and Mann have a number of jelly beans in a ratio of 6 : 1. What is the ratio of Morgan’s jelly beans to Mann’s?

Answer 1

5:3 and 6:1

The 3 and 6 here represent the same number of sweets because they are for the same person, so you need to find a common multiple of these two numbers.

The lowest one is 12. This means the ratios now become:

20:12 and 12:2

This means the ratio of Morgan’s to Mann’s is 20:2

Answer 2

Morgan 10:1 Mann

Explanation:

In this scenario ,

Morgan has 5 jelly beans for every 3 that Kira has,

Kira has 6 jelly beans for every 1 that Mann has.

Therefore, we can multiply both Morgan and Kira's jellybean count by 2 to match Kira's ratio with Mann while still maintaining the ratio with Morgan like so

Morgan 10 :: 6 Kira

Kira 6 :: 1 Mann

Now that we have the same amount for Kira we can see that the Ratio between Morgan and Mann is 10:1
