Answer:
Multiples are 99, 108, 117.
Explanation:
Given,
sum of three consecutive multiples of 9 = 324
to find : the multiples
Solution:
let the multiples be 9x , 9x + 9, 9x + 18
sum of them = 324
9x + 9x + 9 + 9x + 18 = 324
27x + 27 = 324
27x = 324 - 27
27x = 297
x = 297/27
x = 11
9x = 9 × 11 = 99
9x + 9 = 99 + 9 = 108
9x + 18 = 99 + 18 = 117
so the consecutive multiples are 99, 108, 117
What are multiples?
Multiple is the product of any quantity and an integer. In other words, for the quantities a and b, it can be said that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.
There is one another term related to this it is called a factor.
What are factors?
