Question

The sum of 3consecutive multiples of 9 is 54 find these multiples

Answer 1

Step-by-step explanation:

Assume three consecutive numbers : x,x+1,x+2.

The sum of three consecutive multiples of 9 is 324

9x+9(x+1)+9(x+2) = 324

9x+9x+9+9x+18 = 324

27x+27 = 324

27x = 297

x = 11

so numbers are 11,12,13

Smallest multiple = 9*11 = 99
