What does the LCD (least common denominator) of two or more fractions mean?

Answer by  esteban (1334)

The bottom number of a fraction is its denominator. A Least Common Denominator (LCD) is the smallest number that two or more denominators will divide evenly. For example, if you have denominators of 4 and 10, then the LCD is 20, because 4 divides 20 evenly and so does 10.

The LCD is how you make two fractions in the same form. Find the LCM of both denominators and multiply the numerator by the number you did to the bottom.
