  1. Fractions How do we add and subtract fractions with unlike denominators?

  2. 2/5 + 1/3 = 7/9 – 1/6 = Get denominators the same by using LCD (find lcm of the two denominators). How do we add and subtract fractions with unlike denominators.

  3. 2/5 + 1/3 = /15 + /15 = 7/9 – 1/6 = /18 - /18 = Get denominators the same by using LCD (find lcm of the two denominators). lcm of 5 and 3 is 15 lcm of 9 and 6 is 18 How do we add and subtract fractions with unlike denominators.

  4. 2/5 + 1/3 = /15 + /15 = 7/9 – 1/6 = /18 - /18 = Get denominators the same by using LCD (find lcm of the two denominators). lcm of 5 and 3 is 15 lcm of 9 and 6 is 18 Make equivalent fractions. What you did to the numerator, do to the denominator. How do we add and subtract fractions with unlike denominators.

  5. 2/5 + 1/3 = 6/15 + 5/15 = 7/9 – 1/6 = 14/18 - 3/18 = Get denominators the same by using LCD (find lcm of the two denominators). lcm of 5 and 3 is 15 lcm of 9 and 6 is 18 Make equivalent fractions. What you did to the numerator, do to the denominator. How do we add and subtract fractions with unlike denominators.

  6. 2/5 + 1/3 = 6/15 + 5/15 = 7/9 – 1/6 = 14/18 - 3/18 = Get denominators the same by using LCD (find lcm of the two denominators). lcm of 5 and 3 is 15 lcm of 9 and 6 is 18 Make equivalent fractions. What you did to the numerator, do to the denominator. 3. Add or subtract How do we add and subtract fractions with unlike denominators.

  7. 2/5 + 1/3 = 6/15 + 5/15 = 11/15 7/9 – 1/6 = 14/18 - 3/18 = 11/18 Get denominators the same by using LCD (find lcm of the two denominators). lcm of 5 and 3 is 15 lcm of 9 and 6 is 18 Make equivalent fractions. What you did to the numerator, do to the denominator. 3. Add or subtract How do we add and subtract fractions with unlike denominators.

  8. 2/5 + 1/3 = 6/15 + 5/15 = 11/15 7/9 – 1/6 = 14/18 - 3/18 = 11/18 Get denominators the same by using LCD (find lcm of the two denominators). lcm of 5 and 3 is 15 lcm of 9 and 6 is 18 Make equivalent fractions. What you did to the numerator, do to the denominator. Add or subtract Reduce if necessary. How do we add and subtract fractions with unlike denominators.
