How do I work out this problem:5 2/3 - 3 1/6 ? I know the answer is 2 1/2 but how do I arrive at that answer?

I am trying to prepare for a test and I am just learning how to work fractions.

Dolores J.

I understand about 6 being the common denominator but how did we get to 4/6 instead of 2/6? Did you do something to change just that one numerator?

Basically whatever you multiplied the demoninator with, you would multiply the same number with the numerator.


Since I multiplied 3x2 to get 6 as the common demoninator, I would do the same to the numerator: 2 (your numerator) x 2(the # you multiplied to get the common demoninator) = 4.

and so, your fraction would be 4/6.
