common denominator as 15

OpenStudy (anonymous):

6/15 + (5/15 - 3/15)

OpenStudy (anonymous):

OpenStudy (anonymous):

u have to what is in the ( ) 1st

OpenStudy (anonymous):

so 5/15 - 3/15 is 2/15

i have no idea how to evaluate

OpenStudy (anonymous):

then you have 6/15 + 2/15 giving you 8/15

if the denominator is the same in adding and subtracting fractions then you just add or subtract accross the top
