Convert them to improper fractions with a common denominator.

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.

By finding the lowest common denominator of the fractions.

No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.

Yes, but the numerator is different,same as adding fractions

First, turn the fraction into a improper fraction. Then find a common denominator between the two numbers. After this, subtract strait across, but leave the denominator the same.

it stay the same when you subtract fractions and when you add fractions.

Make them into improper fractions, find the least common denominator, convert them, subtract, reduce if possible.

First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators

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.

Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.

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.
