tigerlover (tigerlover):

Is this division or fractions?

OpenStudy (lunarticc):

Fractions , I dont know how to find the lcm of a negative and a positive together

OpenStudy (dumbcow):

when in doubt, multiply denominators together to get lcm ---> 64*15

OpenStudy (lunarticc):

wouldn't i have to simplify it first?

OpenStudy (dumbcow):

no first worry about combining them into single fraction, then simplify

OpenStudy (lunarticc):

fractions are my weakest thing in algebra , okay brb

OpenStudy (dumbcow):

oh i misunderstood , sorry yes first reduce fractions ----> 20/64 = 5/16
