Question

a number is 20 greater than the sum of its one third and one ninth find the number​

Answer 1

Step-by-step explanation:

let the number be X .

Then, required equation

=> X - (X / 3 + X / 3) = 20

=> X - 2x/3 = 20

=> 3x - 2x / 3 = 20

=> X /3 = 20

=> X = 20 × 3

=> X = 60

Hence the required number is 60
