Find the difference between 3 1/12 and 2 1/6. Leave your answer as a proper fraction or mixed number.

Step-by-step explanation:

 Fractions cannot be added or subtracted unless they have the same denominator (bottom number)

    Change to an improper fraction. Multiply the denominator times the whole number (number on the side) then add to the numerator (top number) and place over the the denominator (3*2+1=7→)

-   In order to give both fractions the same denominator, find the least common denominator (LCD = one number that both denominators will divide evenly into) LCD = 6. Then multiply the top and bottom by a number that gives the LCD. We only need to multiply the first fraction  top and bottom by 3.

  This is an improper fraction because the numerator is larger than the denominator. To make a mixed number divide the numerator by the denominator and simplify.
