Question 9289: Hi I am not sure if I am in the right section or not but this is my problem:
The directions say to find the LCD and do not combine fractions.
12/5a^2, 9/a^3
I have tried and tried to figure this out and one of the answers I got was 108/59 and then I read the whole problem and figured out I couldn't put the 2 frractions together. Help!!!! Thank you..

Question 9420: Hi-
I'm confused as to why I am getting the wrong answer to the following problem. I don't understand what I'm doing wrong. Please send email me some help. Thanks
Problem:
3/4 - (-7/12) - 7/8
what I did was find the LCD which I think is 24. So I made the problem as follows:
18/24 - (-14/24) - 21/24 = -17/24
The way that I came up with my answer is:
18/24 - (-14/24) = 4/24 - 21/24 = -17/24
The answer in the back of my book says the answer should be 11/24 and I don't understand how. Thanks in advance for your help.

Question 9421: Hi-
I have a second question that I'm having trouble understanding. If you could please let me know what I'm doing wrong I would appreciate it.
Problem:
- 5/8 - (-11/12)
I found the lcd which is 24 so I made the problem:
-15/24 - (-22/24) = - 37/24
The book says the answer should be 7/24
Why is that if your subtracting 2 negatives.
Please let me know.

Question 13126: I am a mom who is trying to help my 11th grade daughter with her algebra. I remember a while back there being a way to get rid of fractions in an algebra problem but can't for the life of me remember how now. The problem we are trying to figure out is: 9/2(x+3)=27
For some reason I want to put the problem like this to rid the fraction:
9/2 (x/2+3/2)=27/2 I then would do the following but answer not working:
18(2x+6)=54
36x+108=54
36x+108-108=54-108
36x=-54
36x/36=-54/36
x=1.5
I know this isn't right because when I tried to plug it into the equation it didn't work. Could someone please tell me what I am doing wrong to rid problems of fractions?
