Answer provided by our tutors
Let's call the number X.
Translate the wordy problem into an equation.
3*X +1/2 = X + 2/3.
Solve the equation
2*X = 2/3-1/2
To combine fractions, put them over a common denominator. i.e. times the top and the bottom of 2/3 by 2 and the top and the bottom of 1/2 by 3.
2*X = 4/6 - 3/6 = 1/6.
Therefore X=1/12.
