A denominator is the bottom part of a fraction that indicates the total number of equal parts the whole is divided into. It helps determine the value of each individual part represented by the numerator, which is the top part of the fraction. For example, in the fraction ¾, 4 is the denominator, showing that the whole is divided into four equal parts. Understanding denominators is essential for performing operations with fractions, such as addition, subtraction, and comparison.

The greatest common denominator is an infinite amount and not very practical for problem solving.
The least common denominator is the least common whole number all of the numbers are divisible by. 8 can be divided by 1, 2, 4, and 8. 10 can be divided by 1, 2, 5, and 10. 11 is a prime number, this means it can only be divided by 1 and itself. Therefore the least common denominator for 8, 11, and 10 is 1.
yes you would get the same answer. when you use 18 the fraction is just in a different form but should still be the same number. (6 / 9) + (4 / 9) = 10 / 9 = 1.11 (12 / 18) + (8 / 18) = 20 / 18 = 1.11 Just remember to multiply the numerator by the same factor as you do the denominator.
NO!!!! When dividing fractions the steps to take are : - #1 ; Convert to Improper Fractions. #2 ; Very Important ; change the sign to multiply and invert(turn over) the right hand fraction. #3 Then proceed as for multiplication. e.g. 2 1/2 divide 3/4 = 5/2 divide 3/4 = 5/2 X 4/3 NOTE what has happened. Cancel down by '2' 5/1 x 2/3 10/3 3 1/3 The answer.
