subtract? Find a common denominator (LCD is preferred). Convert each fraction to an equivalent fraction with the LCD. Add numerators, keep LCD as new denominator. Reduce the fraction.

The LCD is 9.

For the first fraction, divide the give denominator into the LCD, take that result and multiply by the given numerator to create a new numerator for the LCD. Repeat for each fraction.

Least Common Denominator - pay attention to the lower number in the fraction, if the number on the top of the fraction can divide the lower number (evenly) than you have not reached the LCD.

LCD is the denominators of every fraction in a given collection. Example, 1/2, 4/5, and 3/8 is 40.

It is 12

LCD(9, 3y) = 9y

1/6 is one fraction. You need at least two fractions to find something in common.

First you have to find the LCD. LCD=40 Then you multiply each fraction top and bottom to get 40 as the LCD. 35/40+32/40+18/40 Then you need to add. 85/40 Lastly you simplify. So the answer is 19/8(19 over 8)

I believe it's the LCD, or least common denominator, and continue from there.

The Lowest Common Denominator is needed when adding or subtracting fractions.
