Let's work that out together: 2/15 - 1/12 = 24/180 - 15/180 = 9/180 = 1/20 Here's what we just did: 1. Convert the denominator (lower number) to a common denominator. The easy way here is multiply them (15 x 12). 2. Convert the numerator by multiplying each by the other denominator. 3. Subtract 4. Convert the solution to the lowest factor.
Two quarters minus two thirds is negative one sixth. Two quarters is six twelfths, and two thirds is eight twelfths. Six twelfths minus eight twelfths is minus two twelfths or minus one sixth.

Find the "common denominator". 2/5 is 6/15. So 1 fifteenth minus 6 fifteenths is minus 5 fifteenths , or minus one third
It is eleven twelfths.
Converting to twelfths gives 9 twelfths minus 8 twelfths which is 1 twelfth.
Two quarters minus two thirds is negative one sixth. Two quarters is six twelfths, and two thirds is eight twelfths. Six twelfths minus eight twelfths is minus two twelfths or minus one sixth.
Two fifths is six fifteenths. Eleven fifteenths minus six fifteenths is five fifteenths, which is also one third.
One fourth is three twelfths. So eleven twelfths minus three twelfths is eight twelfths, which is also two thirds.

It is seven fifteenths.
Find the "common denominator". 2/5 is 6/15. So 1 fifteenth minus 6 fifteenths is minus 5 fifteenths , or minus one third
It is eleven twelfths.
Converting to twelfths gives 9 twelfths minus 8 twelfths which is 1 twelfth.
One-third is the same as five-fifteenths. Two-fifths is the same as six-fifteenths. Five-fifteenths plus six-fifteenths is eleven-fifteenths. One, or fifteen-fifteenths, minus eleven-fifteenths is four-fifteenths.
one third? two sixths? three ninths? five fifteenths? six eighteenths? 33%? i could go on forever...
It is: 13/12
Two thirds minus one fourth is equal to five twelfths.
