How do you subtract fractions with mixed numbers and like denominators?
Convert them to improper fractions and proceed.
Can you explain adding and subtracting fractions with like denominators?
When you add or subtract fractions with like denominators, you just add or subtract the numerators and put them over the same denominator. For example, 3/5 - 2/5 = (3 - 2)/5 = 1/5
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 the like fraction?
Like fractions are fractions with the same denominators.
When fractions have like denominators the larger the what the larger the fraction?
When you have fractions with like denominators, the larger is the one with the larger numerator.
