### Fractions

1. 1. Adding and Subtracting Fractions and Different Denominators By Jc ------ ------ -- ------------ (Me)
2. 2. Addition - 3/7 + 4/9
3. 3. Find the Common Denominator <ul><li>3/7 + 4/9 </li></ul><ul><li>7 x 9 = 63 </li></ul><ul><li>9 x 7 = 63 </li></ul><ul><li>* If you can not find a common denominator you can just multiply the two denominators. </li></ul><ul><li>Now multiply the numerator by the same number that you multiplied its denominator by. </li></ul><ul><li>7 x 9 = 63 </li></ul><ul><li>9 x 7 = 63 </li></ul>
4. 4. 27/63 + 28/63 now add the two numerators. 27 + 28 = 55 So the answer would be 55/63
5. 5. The Answer
6. 6. Mixed numbers <ul><li>*If you end up getting a numerator that is larger than the denominator you just divide the numerator by the denominator. </li></ul><ul><li>Ie. 9/4 (9/4 = 2 ¼) so 2 ¼ would be your answer. </li></ul>
7. 7. Subtraction – 2/3 – 2/4
8. 8. Find a common denominator <ul><li>2/3 - 2/4 </li></ul><ul><li>3 x 4 = 12 </li></ul><ul><li>4 x 3 = 12 </li></ul><ul><li>Again, if you can not find a common denominator just multiply the two denominators. </li></ul><ul><li>Now multiply the numerator by the same number that you multiplied its denominator by. </li></ul><ul><li>2 x 4 = 8 </li></ul><ul><li>2 x 3 = 6 </li></ul>
9. 9. now subtract the two numerators. 8 – 6 = 2 So the answer would be 2/12 which reduces to 1/6
10. 10. The answer
11. 11. The End --- --- .. ---------
