    least common multiple you change the denominators so they are equil when you do this you also must change the numerator however EX 1/2-1/3 the least common multiple is 6 so it becomes 3/6-2/6

    by making the denominators equal by multiplying

    |dw:1327948456979:dw| 2/8 Could be divided into 2. Making it 1/4.

    So the answer to my example would be 2/4.

    NO U DONT HAVE TO MULTIPLY THAT CAN MAKE IT A LOT HARDER THAN IT NEEDS TO BE for example if you have 5/6 + 3/12 you can just multiply both the numerator and denominator of 5/6 by 2 and you get 10/12+3/12
