what about 14/16-6/16
OpenStudy (anonymous):
just susubtracting correct?
OpenStudy (anonymous):
yeah and in simplest form
OpenStudy (anonymous):
8/16 = 1/2
so 1/2 is simplest form
OpenStudy (anonymous):

like 5/7+3/8
OpenStudy (anonymous):
we'll take LCM
OpenStudy (anonymous):
7 * 8 = 56
so
(5/7)*(8/8)
(3/8)*(7/7)
40/56 + 21/56
now we have same denominator
add them
61/56
OpenStudy (anonymous):
I hope you understand it :)
OpenStudy (anonymous):
