OpenStudy (alexandervonhumboldt2):
you caanot subtract before you make denominators equal

the common is 25
OpenStudy (alexandervonhumboldt2):
6/25 - 4/5=6/25 - 20/3=25=-14/25
OpenStudy (anonymous):
so i would use 25 as my common denominator?
OpenStudy (anonymous):
4/8 - 2/3
8*3= 24
4/8=12/24
2/3 = 16/24
12/24-16/24= 1/2 - 2/3
= -1/6
