7:30 – 9:00 More Fraction Practice
To Add Fractions:
1. We need to find something called the least common denominator (LCD).
2. Then, we add the numerators.
3. The denominator of your answer will be the same denominator of the built-up fractions.
4. As always we have to reduce or simplify the answer, if needed.
Note: We Do Not Add denominators!
To Subtract Fractions:
1. We need to find something called the least common denominator (LCD).
2. Subtract the numerators of the fractions.
3. The denominator of the answer will be the common denominator or the denominator of the built-up fractions, whichever applies.
4. Reduce or simplify the answer, if needed.
Note: We Do Not Subtract denominators!
To Multiply Fractions:
Multiply the numerators.
Multiply the denominators.
Simplify or reduce the resulting fraction, if possible.
2/3 X 4/5 = (2 X 4)/(3 X 5) = 8/15
Dividing Fractions
To divide fractions, convert the division process to a multiplication process by using the following steps.
Change the “÷” sign to “x” and invert the fraction to the right of the sign.
Multiply the numerators.
Multiply the denominators.
Re-write your answer in its simplified or reduced form, if needed.
