Question

The ratio of two numbers is 3:5, the smallest number is 45 what is the larger number?

Answer 1

x = larger number

45 / x = 3 / 5 Multiply both sides by 5

45 * 5 / x = 3

225 / x = 3 Multiply both sides by x

225 = 3 x Divide both sides by 3

225 / 3 = x

75 = x

x = 75


Proof:

45 / 75 = ( 3 * 15 ) / ( 5 * 15 ) = 3 / 5
