Question

a number added to one third of itself equals 12. What is the number​

Answer 1

Answer:

let the number be 'x’

according to condition

x+x/3 = 12

3x + x/3 = 12

4x = 36

x = 9

the number will be 9

Answer 2

$= > \: 1 + \frac{1}{3} x = 12$

$= > \: \frac{(3x + 1x)}{3} = 12$

$= > \: 4x = 12 \times 3$

$= > \: x = \frac{36}{4} = 9$

So, a number when added to one-third of itself equals to 12 = 9.
