Written as improper fractions, divide the numerators (converting any resulting improper fraction to a mixed number if required).
However, I would rather not remember this short cut as it could result in being used inappropriately (when the denominators are different), but instead stick to using the standard method, writing out the calculation in full and cancelling down before doing the actual multiplications.
The same way as mixed numbers without like denominators:
- Convert the mixed numbers into improper (top heavy) fractions.
- Invert (turn upside down) the divisor.
- Multiply the fractions together (by multiplying the numerators together and the denominators together).
However, with the same denominators, in inverting the divisor it will mean that its numerator is the same as the denominator of the [original] dividend and so will cancel, leaving the result as the numerator of the first improper fraction over the numerator of the second - dividing the improper fractions' numerators.

Do you have to regroup mixed numbers that have like denominators when subtracting them?
No
How do you add mixed numbers with like denominators?
To add mixed numbers with like denominators, first add the whole numbers, then add the fractions. For example: 2 2/3 + 4 1/3 = ?? First add the whole numbers. 2 2/3 + 4 1/3 = 6? Then add the fractions. 2 2/3 + 4 1/3 = 6 3/3 Simplify. 3/3 is one. 2 2/3 + 4 1/3 = 6 + 1 = 7.
How do you add or subtract rational numbers with common denominators?
you subtract the top 2 numbers and then leave the denominators the same like: 7/8-4/8=3/8. Get it?
How do you devide a fraction with a mixed number?
*divide transform the mixed number into a fraction and then divide like a normal fraction (multiply by reciprocal).
What are fractions with unlike denominators mean?
The denominator is the bottom number in a fraction. Fractions like 1/3 and 1/4 have different numbers on the bottom. Those are unlike denominators.
Do you have to regroup mixed numbers that have like denominators when subtracting them?
No
How do you subtract fractions with mixed numbers and like denominators?
Convert them to improper fractions and proceed.
How is dividing mixed numbers like dividing fractions?
you cant divide mixed numbers
How do you add and subtract mixed numbers?
SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.
How do you add mixed numbers with like denominators?

How do you add or subtract rational numbers with common denominators?
you subtract the top 2 numbers and then leave the denominators the same like: 7/8-4/8=3/8. Get it?
How would you add or subtract fractions with like denominators?
The same way you would add or subtract whole numbers, leaving the denominators alone.
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.
How do you devide a fraction with a mixed number?
*divide transform the mixed number into a fraction and then divide like a normal fraction (multiply by reciprocal).
How do you divide fractions with like denominators?
Simplify the denominators and divide the numerators. Example: 8/5 ÷ 2/5 = 8/2 = 4 Check: 8/5 ÷ 2/5 = 8/5 x 5/2 = 8/2 = 4
How do you add and subtract rational numbers with unlike denominators?
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.
Can 14 be written as a mixed number?
Whole numbers like 14 are not normally converted into mixed numbers
