Answer 2

Answer:

hey there!!

Let the one no. be x

and the other no. be 7x

the sum of the two nos. = 720

                                x+7x= 720

                                  8x= 720

                                   x= 720/8

                                  x= 90

therefore; one no. x = 90

                 other no. 7x=630
