Convert them to improper fractions with common denominators and proceed.
No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
find GCF(Greatest Common Factor) then subtract
multiply the fractions until they have common denominators and then subtract them
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.
You first find equivalent fractions whose denominators are a common multiple of the different denominators. Teachers like you to use the least common denominator: that is not necessary although it can result in your working with smaller numbers and so make things easier.

Common denominators are common multiples of two or more denominators.
When you are trying to add or subtract fractions with different denominators.
It will enable you to add and subtract fractions with unlike denominators.

The denominators need to be the same for subtraction. Find the Least Common Denominator for both items and then subtract.
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.
If the denominator is the same, you just add the numerators - just as with plain numbers.
Whether the denominators are common or not.
