The ratio between Mahmoud's money and Amr's money is . If the sum of their money is LE, how much money does Mahmoud have?
The ratio between Ayman's money and Aya's money is . If the sum of their money is LE, how much money does Ayman have?
We can use the concept of "the sum of parts" to solve this problem.
The ratio of Ayman's money to Aya's money is , or . So, Ayman's money = 11 parts, and Aya's money = 14 parts.
The sum of their money = 11 parts + 14 parts = 25 parts.
Since 25 parts = LE, then one part = LE.
Ayman's money is equal to 11 parts, so we can multiply the value of one part by 11 to find how much money he has: LE.
