Question

A number is twice as much as a number, the second number is twice as much as the third number. If the sum of three numbers is 84, what is the smallest number?​

Answer 1

Answer:

12

Step-by-step explanation:

Let smallest number be x.

Then,

x+2x+4x=84

7x=84

x=12

Answer 2

let a number :x

let second number:2x

let third number:3x

so the equation is :x+2x+3x=84

6x=84

x=84/6

x=14

so,

first number :x=14

second number:2x=2x14=28

third number :3x=3x14=42
