Answer: 13/5
Explanation X/Y = 3/2 So X = 3Y/2 (X^2 + Y^2)/(X^2 - Y^2) Now replace the X value from first equation = [ (3Y/2)^2 + Y^2] / [ ((3Y/2)^2 - Y^2] = [ (9Y^2/4) + Y^2] / [ (9Y^2/4) - Y^2] = [ (9Y^2 + 4Y^2)/4] / [ (9Y^2 - 4Y^2)/4] = (9Y^2 + 4Y^2) / (9Y^2 - 4Y^2) = 13Y^2 / 5Y^2 = 13/5

Answer: 10:11
Explanation To find the ratio between their ages, we need to convert their ages to a common unit (months): Ashraf's age: 15 years × 12 months/year = 180 months - 10 months = 190 months Akmal's age: 17 years × 12 months/year = 204 months - 5 months = 209 months Now, find the ratio: Ashraf's age : Akmal's age = 190 : 209 Simplify the ratio: 190 ÷ 19 = 10 209 ÷ 19 = 11 So, the ratio is: 10 : 11
