First you need a common denominator: 3/4 and 5/8, the common denominator is 8. (4x2=8, 8x1=8) Multiply both the numerator and denominator of 3/4 by 2 so that it becomes 6/8. Now that a common denominator is established, you may subtract them with ease. 6/8 - 5/8 = 1/8.
The common denominator of 5/8 and 3/4 is 32.The lowest common denominator (LCD) is 8.The highest common denominator (HCD) is 32.
If that's 3/4 and 5/6, the LCD is 12.
