Ivan and tanya share ? 150 in the ratio of 4: 1 work out how much more ivan gets compared to tanya

Hi!

Since the ratio is 4:1, that means that the total amount of parts considered in this ratio is 4 + 1 = 5.

Total sum of money is 150$, and the number of parts is 5.

150/5 = 30$ is the amount of one part.

Knowing that, we further know that Ivan has 4 parts and Tanya has 1 part, which is 120$ and 30$, respectively.

Due to that, we are now dividing Ivan's amount by Tanya's amount : 120/30 = 4, so Ivan has 4 times more money compared to Tanya.

Hope this helps!
