5/-11 +1/4

OpenStudy (anonymous):

find a common denominator first

OpenStudy (anonymous):

after you find the common denominator, figure out what you need to multiply each denominator by to get the common denominator

OpenStudy (smurfy14):

-9/44

OpenStudy (anonymous):

i would mulitple -11 by 4 and get 44

OpenStudy (smurfy14):

common denom is 44 so it turns into -20/44 + 11/44 which gives you -9/44

OpenStudy (anonymous):

I will happily help you figure it out step by step, but I won't give you the answer.

OpenStudy (anonymous):

so when i have a fraction like this i find a denmotarthen subtract

OpenStudy (anonymous):

So, you want to find the LEAST common denominator

OpenStudy (anonymous):

this will not always be just the 2 denominators multiplied together

OpenStudy (anonymous):

for example...

OpenStudy (smurfy14):

ya find lcd then subtract or add or whatever it tells you to

OpenStudy (anonymous):

oki th i got it now

OpenStudy (anonymous):

if you have something like 1/2 and 1/4

OpenStudy (anonymous):

don't multiply..use 4 because it's the lowest common number that each of them can be divided into

OpenStudy (anonymous):

so a commondemon would b 4

OpenStudy (smurfy14):

ok and if you dont mind could you click the blue good answer button on the far right? thanks:)

OpenStudy (anonymous):

sorry i can't type over top of someone else typing..

OpenStudy (anonymous):

do you want more help or have you got it figure out?

OpenStudy (anonymous):

i got this onebut i hae others

OpenStudy (anonymous):

ok, well i'm happy to walk you through and let you figure them out, but i'll be annoyed if people just pop the answers out

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

I was going to give you an example of something where you have to find an LCD, but it doesn't involve multiplying denominators
