# Guess a fraction

Tom was asked to guess a fraction. The sum of 1/2 the numerator and 1/3 of its denominator is 30. If Tom subtracts 36 from its denominator, the fraction becomes 1/3. What is the fraction that Tom was asked to guess? (Leave your answer in simplest form)

Correct result:

d =  72
n =  12
f =  0.1667

#### Solution:

n/2+d/3=30
n= (d-36)/3

2d+3n = 180
d-3n = 36

d = 72
n = 12

Our linear equations calculator calculates it.
$f=n\mathrm{/}d=12\mathrm{/}72=\frac{1}{6}=0.1667$

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
