A boy is 26 years younger than his father. In 3 years' time his age will be 1/3 his father's age. Find the boy's present age

10 years

Step-by-step explanation:

let age of the boy x , and let age of his dad y

x - y = 26

y + 3 = (x+3) / 3

x - 26 = (x+3) / 3

3x - 69 = x + 3

2x = 72

x = 26, y = 10

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

answer: -0.5 would be the most likley outcome
