Question

One number is 1/5 of another number. the sum of the two numbers is 1818. find the two numbers.

Answer 1

Let x represent one of the numbers, then the other number is (1/5)x

Sum:        x + (1/5)x = 1818
         (5/5)x + (1/5)x = 1818
                 (6/5)x      = 1818
                     6x        = 9090
                       x        = 1515

(1/5)x = (1/5)·1515 = 303

Answer: The two numbers are 303 and 1515
