Proportions can be used to solve problems in a variety of applications. What are some examples where this method could be used to solve a problem?

Eg.

1. Suppose you need (1/4) cup of milk to make 15 ice-creams, then How much milk would you need to make 25 ice-creams?

2. The exchange rate from dollar to euro is $1 = 0.89 Euro, then How many euros will you get, if you have $100 in your pocket?

Let me know in the comments, If you need anything else.
