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.

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 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.
How do you add and subtract by fractions?
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
How do you do subtract fractions?
One way you can subtract fractions is to change them into decimals, aligning the decimals vertically, then subtracting like you would with whole numbers, making sure to carry down the decimal. Another way that you can subtract fractions is to use the least common denominator (lcd). First, simplify the fractions. Then find the multiples of the denominators. When you find the multiple included in both lists that is the least, multiply the numerator and denominator by the same number in order to make the denominator into the lcd. Then, subtract the numerators and simplify the answer. Example: 2/3 - 1/2 = 4/6 - 3/6 = 1/6

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.

What are fraction that have same denominator called?
They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.
Why do you need a common denominator?
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
What are like and unlike fractions?
Like fractions are the fractions which have the same denominator and unlike fractions are the fractions which do not have the same denominator.
How do you use prime factorization to subtract fractions in math?
Finding the prime factorizations of the denominators will help you find the least common denominator. Converting to equivalent fractions with like denominators will allow you to subtract them successfully.
How do you subtract mixed numbers and borrow from the whole number?
you subtract mixed numbers by changing them to improper fractions. to borrow from a whole number you take away one like 5 changes to 4 and then you change look to the other mixed number your subtracting by and write its denominator as 4s denominator.
