I got an idea
oh my I didn't study for my test
First you don't know if it is going to be a uncommon denominator or a like let me take you through both so im going to do like first.
So if i had 2/4 plus 1/4 you don't add the denominators you just need to add the numerators. By the way if you didn't know what a numerator meant it is the top number the denominator is the bottom number so if you add them you will get 3/4.
When you add unlike denominators you have to find your least common denominator so if i added 4/6 plus 2/4 you need go to see your multiples of the six first 6 12 18 now the four 4 8 12 what is first 12 so we have common denominators so now we have 2/12 plus 4/12 that is 6/12 and if you wanted to make it shorter 1/2 because 6 is 1/2 of 12
Now if I wanted to subtract 10/12 from 5/12 remember you dont subtract the denominators you subtract the numerators so if you just do 10 -5 that will be 5 but when you add one denominators. You will get 5/12 your answer .
GET it now .
Last thing how to subtract unlike denominators so if I do 3/4-1/2 we need to find the multiples of both denominators so three first. 369.Now the two 246 .WHAT do we see that 6 are in both .Now we have 3/6-1/6 which is 2/6.
Yes I get it now I can and study for my test
