2/3 and 3/4

Looks like 12 here, so use form of one to convert both fractions to LCD form.

4*2/4*3 and 3*3/3*4

8/12 and 9/12

Because 5 and 3 are both prime the LCD is the product of the two:

5 * 3 = 15.

You need at least two fractions to find something in common.

The LCD is 12.

the LCD of 2, 9 and 5 = 90

If that's 84 and 35, the LCD is 420.If that's 8/4 and 3/5, the LCD is 20.

The LCD, or Lowest Common Denominator, is the smallest multiple of each of the denominators of a set of fractions. So, assuming that 2, 4 and 5 are denominators of fractions (1/2, 1/4 and 1/5, for example), the LCD would be 20, because 20 is the lowest number that 2, 4 and 5 multiply into. So, your new fractions would be 10/20, 5/20 and 4/20. The purpose of finding the LCD is to allow for multiplying fractions together, or simply comparing them easily.
