subtraction
You first need to find a common denominator, not necessarily the least common denominator. Next, you rename the fractions according to the common denominator. Only then can you subtract the fractions. After subtraction you should simplify the answer.
It really doesn't matter whichever one you are more comfortable with. fractions are a bit more challenging to convert.
You should not have any remainders in fractions!
Basic addition and subtraction.
you should use addition in a problem involving fractions if you see key words that mean to add, for example sum increase, altogether, etc

Reduce it, if possible.

Yes they should
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
You should not have any remainders in fractions!
It does not matter what they are as long as both are the same. 1 = 2/2 = 17/17 = 958/958 and so on.
You should keep your attention focused on your work at all times - not just when working with addition or subtraction!
