to add a fraction, get a common denominator, then add the numerators.
example:
2/10+4/5
first get common denominators
2/10+8/10
then add the numerators
10/10
(simplify)
1
to subtract from a fraction, get common denominator, then subtract the numerators.
example:
4/5-2/10
first get common denominators
8/10-2/10
then subtract the numerators
6/10
(simplify)
3/5

How do you check you math with adding fractions?
When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly
Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
What do adding and subtracting mixed numbers means?
To combine the fractions or subtract the fractions. Same method with mixed numbers.
Are adding fractions the and subtracting fractions the same?
Adding and subtracting fractions are similar processes, but they involve different operations. Both require a common denominator to combine the fractions. When adding, you combine the numerators, while subtracting involves finding the difference between the numerators. Thus, although the steps are alike, the outcomes differ based on whether you are adding or subtracting.

What did you learn from adding and subtracting fractions?
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
