Find a common denmoniator
so we could multiply the top fraction to get 12x
What is LCM of 3, 4, and 8?
Good. Now get a common denominator of 24 in the numerator and the denominator.
How do I do that?lol
nvm! I got it!
Multiply the numerator and the denominator of each individual fraction by the appropriate number.
would it be 6x/25 + 8y/24 divided by 8x/24 - 3y/24
the ldc would be 12 for the top and 24 for the bottom
Keep them the same
6x/24 + 8y/24 divided by 8x/24 - 3y/24
would it e 8x-24 - 3y/24
then flip the 2nd fraction
(6x + 8y)/(8x - 3y)
3x+4y/ 4x-3y as the answer
Ok, I understand:)
Thanks for trying :)
not quite, it doesn't work that way with division :)
you can keep it that way because that is simple enough
ok:) Thanks so much!!!!
After the fraction x plus 1 all over 2 minus the fraction x plus 2 all over 3 x have been combined using the least common denominator of 6x, what is the numerator?
This one is easy, I just need someone to check it:)
write it out
−x2 + 4x + 2 3x2 + x − 2 −3x2 − 4x + 2 3x2 + x − 4
I think it's B?
You need a better reason :)
Lol okay, I'll try
Please do try.
see how I am not completely multiplying the denominator to obtain the LCD when variables are involved? it is a trick so you won't have to do extra work since you will immediately see that when you divide, it cancels out the other.
Ok! It kinda makes sense now. Hmmm...so D?
you have to finish the work :P we do not give out answers
then you'd get 3x^2+x-4.
Multiply out the numerator and simplify
