How do you find the difference of two fractions with the same denominator?
Subtract as if there were no denominators.
How do you subtract fractions with a common denominator?
If the two bottom numbers are the same, you will carry that same number over to the denominator in the answer. To get the numerator (top number) simply subtract the two numerator and place the number over the answer denominator.
How to add fractions having similar numerators but different denominators?
The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
When you add or subtract two like fractions when does the final answer have a different denominator?
Never. You could write a fraction as a mixed fraction if you like and then the mixed fraction would have a different denominator (e.g.: 23/2 = 11 1/2)
How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
