Why doesnt the denominator change when you find the difference between to fractions?
the best way i can answer that question is this: whats 2+1? it's 3. really, 2=2/1, and 1= 1/1. the denominatior doesn't change there either, because they're the same. the only time a denominator changes in fractions is when the denominators are different. (i.e. 2/3 + 3/5= 19/15. [in this case, you have to multiply the 2 on the top of 2/3 with the 5 on the bottom of 3/5. then you have to multiply the 3 on the bottom of 2/3 with the 3 on the top of the 3/5. the product of the 2 numbers are ther numerator; on top. the multiply the 3 and the 5 on the bottom of the fractions: the product of those numbers are the denominator: what go on the bottom of the fraction. 2x5=10, and 3x3=9. 10+9=19 (goes on top). then, 3x5-15 (goes on bottom.) the answer would be 19/15. i hope that answers your question.

Do you need to change the denominator when multiplying fractions?
No.
How do you change a fractions to a decamals?
To change fractions into decimals divide the numerator by the denominator as for example 3/4 = 0.75
What is the difference between multiplication and division fractions?
In dividing fractions you have to change division to multiplication and change the second fraction into a recipracol(flip the fraction.
How do you find the difference between two fractions?
Change the fractions so that they have a common denominator. Then subtract the two numerators and put the result over the common denominator. Example: Difference between 1/3 and 1/4. First change the fractions so that they have common denominators: 4/12 and 3/12. Subtract the numerators: 4-3=1 Answer: 1/12.
How do you order fractions with unlike denominators?
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.
What are two fractions between two thirds and one fourth?
Two fractions between 2/3 and 1/4 are: 1/3, 1/2 To find fractions in between two fractions, simply change the denominator of the fraction. It is sometimes easier to express the two fractions with a common denominator if there is a significant difference between them. For instance, express 2/3 and 1/4 as 8/12 and 3/12, respectively. You can see that there are atleast 4 fractions between the two.

How do you change equivalent fractions to decimals?
Divide the denominator into the numerator.
What is the rule for subtracting fractions?
First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).
