You want to know? It's like that. First, if this question, like that:
1/9 + 2/8 =
The denomanator, the bottom number is special.
9x1 =9
9x2= 18 and then on.
also 8. We will need to check if any answers are the same. and find the LCD, like the Least denomantor. So the answer the same is. Divide it by the denomanator before, and times the numerator to find the numerator for each of the numbers. Then put the denomanator on the bottom and add it. To add it, the denomanator of the answer will be the same as the answer you found. Then, the numerator, the top number will be subtracted like normal. This is a easy way, but many steps. The add will be like that too!
do these:
1/5 + 3/7=
2/7 - 5/8=
Hope you enjoy! If you got them wrong, do these.
4/8 + 7/9 =
8/9 - 5/9

How do you subtract mixed number with different denominator?
Convert them to improper fractions with a common denominator.
Mixed numbers combine fractions and percents?
True
When adding fractions do you change mixed numbers into improper fractions?
not necessarily no not unless the prompt ask you too then i suggest you shouldn't it is quite simple to do without and in my opinion MUCH easier.
How do you change a mix fraction to a proper fraction give an example?
Mixed fractions can't become proper fractions. Mixed fractions are greater than one.
Why are equivalent fractions important when adding and subtracting fractions?
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
