Adding+unlike+fractions

= Adding Unlike Fractions = = = = __Here are the steps to adding unlike fractions__ = Find least common multiple. Multiply top and bottom by the same number to get the like fractions. Add the fractions. **here is a example**
 * A plank is painted 1/2 red and 1/3 green. The rest is painted yellow. What fraction of the plank is painted red and green?**

1/2+1/3=?

List the some multiples of the denominators, 2 and 3. Some multiples of 2 are: 2,4,6,8. Some multiples of 3 are: 3,6.9,12. The least common multiple of 2 and 3 is 6. So, 6 is the least common denominator of 1/2 and 1/3. Use it to rewrite 1/2 and 1/3 as like fractions.
