It is 10/60, which can be simplified, if required. No point in simplifying if you want to add up lots of fractions of an hour, though.
The same way you calculate averages with whole numbers: Add up all the fractions and divide by the number of fractions there are.
Example, add 0.3 + 0.5, which equals 0.8...convert these to fractions and you see they both have the same denominator: 10 so, it would be the same as 3/10 + 5/10...since they have the same denominator adding the fractions topgether would be (3+5)/10 or 8/10. This is the same result as lining up the decimals and adding the digits: 0.3 + 0.5 = 0.(3+5) = 0.8
Dissimilar fractions have different denominators and their lowest common denominator must be found in order to add them up.
1/4 and 1/4
The answer to this tautological question is: 10.
The fractions could add up to a whole number.
1/10+1/10=2/10 which reduces to 1/5

I believe there is only one difference. The mixed numbers have to be converted to fractions. After that the operation is the same. Each fraction then must have a common denominator in order to add or subtract which is true in either case. Perhaps you need to convert back to mixed number however you might have to do that also when adding fractions. Example 9/16 +9/16 =18/16 = 1 1/4. And in subtracting mixed numbers you might end up with a complete fraction thus not needing conversion. Therefore I see only one definite difference as described above on the first paragraph.

As a mixed number it is 105 and 7/10 which add up to 105.7
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.
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.
Example, add 0.3 + 0.5, which equals 0.8...convert these to fractions and you see they both have the same denominator: 10 so, it would be the same as 3/10 + 5/10...since they have the same denominator adding the fractions topgether would be (3+5)/10 or 8/10.
