What do you call a fraction with the same denomanator?
They are like fractions.
How do you know when two fractions are equivalent?
You have to get a common denomanator to then work out if the numerator is also the same.
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,
Do you have to have the same denominator when you subtract fractions?
Yes, but the numerator is different,same as adding fractions

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 subtract fractions with same denominators?
you subtract the numerators, and leeave the denomonators alone
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 subtract mixed fractions by simple fractions?
You want to know? It's like that. First, if this question, like that: 1/9 + 2/8 = The denomanator, the bottom number is special. 9x1 =9 9x2= 18 and then on. also 8. We will need to check if any answers are the same. and find the LCD, like the Least denomantor. So the answer the same is. Divide it by the denomanator before, and times the numerator to find the numerator for each of the numbers. Then put the denomanator on the bottom and add it. To add it, the denomanator of the answer will be the same as the answer you found. Then, the numerator, the top number will be subtracted like normal. This is a easy way, but many steps. The add will be like that too! do these: 1/5 + 3/7= 2/7 - 5/8= Hope you enjoy! If you got them wrong, do these. 4/8 + 7/9 = 8/9 - 5/9
Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
How are fractions under addition?
In order to add or subtract fractions, they must have the same denominator.
What is the process of subtracting fractions?
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
