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!
Ivan gets £90 more compared to Tanya
