Question

Convert the following word problems in a mathematical form:

Answer 1

Answer:

Let smallest multiple be x

so others two are x + 6 , x + 12

by the condition given in your question we get equation

x + x + 6 + x + 12 = 666

3x + 18 = 666

3x = 648

x = 648/3

x = 216

x + 6 = 222

x + 12 = 228

so three multiples are 216 , 222 , 228
