You have to make the denominators equivalent by multiplying to get a "common denominator." For example, if you have
6/5 - 3/4, you figure that 20 is the smallest number that can go into both of the denominators, so you have to multiply the reciprocal by whatever number you have to multiply to get that denominator.
6/5 has to be mulitplied by 4 to get a denominator of 20= 24/20
3/4 has to be mulitplied by 5 to get a denominator of 20= 15/20
Now you can subtract and the answer is 9/20.
What else can I help you with?
Do you add and subtract like and unlike fractions in the same way?
no, to add and subtract like and unlike fractions the denominator has to be the same,
Why are two fractions converted into like fractions?
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
How do you subtract fractions with like denominators?
Subtract the numerators as we normally subtract them and then divide the resultant by the denominator. It's just simple like that.
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How do you subtract fractions with mixed numbers and like denominators?
Convert them to improper fractions and proceed.
Why is it necessary to convert two fractions into like fractions before adding and subtracting them?
Because think of like fractions as the same things.. you can subtract halves from halves for example, but what does it mean to take away a half from a third?By converting them into like fractions, we can add or subtract them easily.
How do you add and subtract fractions with the same denominator?
it stay the same when you subtract fractions and when you add fractions.
How do you add and subtract dissimilar fractions?
Make the fractions equivalent then subtract
How do u subtract fractions?
multiply the fractions until they have common denominators and then subtract them
Why do you have to turn unlike fractions into like fractions to add or subtract?
because its just one of the rules of math :)
Why do you need a common denominator with fractions?
You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.
