What are unlike mixed numbers?
the fractions have different denominators
What is the first thing you should look for when adding or subtracting fractions or mixed numbers?
common denominators.
How do you add and subtract mixed numbers with unlike denominators?
just change the fration with the smallest denominator and add or subtract the way you always do.
Do you have to regroup mixed numbers that have like denominators when subtracting them?
No
How would you add two mixed numbers that contain unlike fractions?
you would convert the mixed numbers into fractions where the top number is greater than the bottom number, then multiply both the numerator and the denominator by a number that makes the denominators the same.

When adding mixed numbers what number are you supposed to find the least common multiple?
the denominators
Do you Add both the numerators and the denominators when adding fractions and mixed numbers?
False [ I THINK ]
What is the first thing you should look for when adding or subtracting fractions or mixed numbers?
common denominators.
How do you add two negative mixed numbers and one positive mixed number?
Convert them to improper fractions with common denominators and proceed with the adding and subtracting.
How do you add and subtract mixed numbers with unlike denominators?
just change the fration with the smallest denominator and add or subtract the way you always do.
Do you have to regroup mixed numbers that have like denominators when subtracting them?

How is adding mixed numbers different from adding fractions?
when you add mixed numbers you have a whole number but adding fraction does not.
Why do you change mixed numbers to improper fractions before multiplying and dividing?
Because common denominators allow adding and subtracting of numerators. Improper fractions also have simplified rules over mixed numbers when performing multiplication and division.
How is adding mixed numbers the same as adding fractions?
Mixed numbers can be converted to improper fractions. Then, it is exactly the same as adding proper ones.
When adding two mixed numbers is it always necessary to rename the fractional sum explain?
When adding two mixed numbers, it is not always necessary to rename the fractional sum, but it can make the calculation easier. Renaming the sum involves converting the mixed numbers to improper fractions, adding the fractions, and then simplifying the result back to a mixed number if needed. This process can help avoid dealing with larger denominators and make the addition more straightforward.
