To determine which fraction is larger, we need to find a common denominator. In this case, the least common denominator is 8. When we convert 3/4 to have a denominator of 8, we get 6/8. Comparing 6/8 and 5/8, we can see that 6/8 is larger, so 3/4 is greater than 5/8.
If that's 8 and 1/8 and 16 and 1/4, the LCD is 8.
The common denominator is usually the Lowest (or Least) Common Multiple of the numbers involved. Where two numbers have no common factors then the LCM is simply the product of those numbers. As 19 is a prime number and has no factors in common with 18 then the common denominator is 18 x 19 = 342.
A common denominator 24.
