Question

2/3 of a number is 20 less than the original number find the original number

Answer 1

Answer: 60

Step-by-step explanation:

Let the original number be 'x'

Given - 2/3 of x = x - 20

2/3 *x = x - 20

by transposition

2/3*x - x = - 20

2/3*x - x/1 = - 20

LCM of  3 and 1 is 3

2/3*x - x/1 * 3/3 = - 20

2/3*x - 3/3*x = -20

-1/3*x = -20

1/3*x = 20

x = 20*3

x=60
