you round fractions by rounding up or down, you can decide to do this when you look at the numerator and decide if it is half of the denominator, if it is half or more than half, you round up. If it is less than half you round down. Another way you can round fractions is dividing the top number by the bottom number (with a calculator), then if the decimal part is 5 or more, round up! (if the decimal is less than 5, round down.)
to maybe split things up or cut them in half or 1 3rd or 1 4th
1/15 + 1/15 + 1/15
Well, darling, 1 half plus 1 eighth is simply 5 eighths. It's not rocket science, honey. Just add those fractions up and voilà, you've got your answer.
Six quarters adds up to one and a half. If we are talking about the coins, they add up to $1.50 in change.
1/4 and 1/4
one half, one third, and one sixth

5/8 add both fractions up then divide by 2
Well let's say that you have the mixed number one and a half. The one counts as 2 two's. Then you add the two two's with the other two that made up the half and get three over two.
The same way you calculate averages with whole numbers: Add up all the fractions and divide by the number of fractions there are.
The answer to this tautological question is: 10.
They didn't. It isn't supposed to add up to one, rather fractional amounts can be formed by adding various combinations of the fractions. If the eguptions needed to represent the value 1, they wouldn't do it with fractions.

You need to learn fractions because they show up in every day life. You can for example say that someone can half of your lunch.
If the fraction is less than half, round down. If the fraction is half or greater, round up.
