5/-11 +1/4
find a common denominator first
after you find the common denominator, figure out what you need to multiply each denominator by to get the common denominator
-9/44
i would mulitple -11 by 4 and get 44
common denom is 44 so it turns into -20/44 + 11/44 which gives you -9/44
I will happily help you figure it out step by step, but I won't give you the answer.
so when i have a fraction like this i find a denmotarthen subtract
So, you want to find the LEAST common denominator
this will not always be just the 2 denominators multiplied together
for example...
ya find lcd then subtract or add or whatever it tells you to
oki th i got it now
if you have something like 1/2 and 1/4
don't multiply..use 4 because it's the lowest common number that each of them can be divided into
so a commondemon would b 4
ok and if you dont mind could you click the blue good answer button on the far right? thanks:)
sorry i can't type over top of someone else typing..
do you want more help or have you got it figure out?
i got this onebut i hae others
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
ok
I was going to give you an example of something where you have to find an LCD, but it doesn't involve multiplying denominators
