Can u simplify when adding fractions?

Question

Can u simplify when adding and subtracting fraction ?

Answer 1

yes

Answer 2

simplify when adding/subtracting - not until you get the sum or the difference

they must have the same denominator to + and -

THEN - you can simply when finished

all the best

Answer 3

They can; there are two cases in which this can be done, and this example covers both of them:

3/6+1/2

notice that you can reduce 3/6 to one half before you add the fractions; this is the first case. The second follows:

3/6+1/2=1/2+1/2=2/2

This second case is when the answer to the addition can be simplified; notice that 2/2 can be simplified to 1. I hope this helps :)

Answer 4

20/40 - 10/40 = 10/40

10/40 = 1/4

does that help?

Answer 5

You need to get a common denominator. You can simplify before you solve the problem but the denominators need to match.

Answer 6

yea if its reduace able such 2/4 it reduces to 1/2 and if its a improper fraction such as 4/2 then it would 2/1 some teachers dont really care and they let you leave it as a improper frac.  

Answer 7

Sometimes.

Answer 8

you can only add fractions if the denominator[bottom #] is the same in all the factions to be added. then you add up the numerators[top#]. once you have done that you can simplify your answer. subtraction uses the same process.

Answer 9

you can if the fraction can be simplified.
