__ ADDING FRACTIONS WITH DIFFERENT DENOMINATORS: __



Remember that we need the denominators to be the same to add a fractions' numerators

But what if the denominators are different???

Then find a multiple of the denominators that is a common multiple of both, it becomes the new denominator!

This number is referred to as the __ Common Denominator __

Next multiply the numerator by the same number that was used to get the common denominator



HOW ?!?!?!?!?!!?! 1 st : Find the Common Denominator by listing out multiples of the denominators (2 & 3)

2: 2, 4, 6, 8, 10, 12 3: 3, 6, 9, 12, 15

Choose the __Lowest/smallest__ common multiple ===> In this case 6

1/2 becomes 6, ? = 1 X 3 = 3 1/3 becomes ??/6, ?? = 1 X 2 = 2 1/2 becomes 3/6 1/2 becomes 2/6

And so

Check out this cool video about adding fractions ... BTW its FUN !!!!!
