If the ratio of two positive numbers is 7 : 9 and their product is 1575, then the greatest number is

Given ration 7 : 9 So, let the numbers be 7a and 9a. According to the question - 7a * 9a = 1575 63a² = 1575 a² = 1575/63 Or a² = 25 And a =5 So, the two numbers will be - 7a = 7 * 5 = 35 And 9a = 9 * 5 = 45 Hence, the greater number is 45 between the given numbers.
