Please Help =( - School & Work

*~*Cori*~* · 02-08-2006, 11:55 PM

I don't get this math... I know most anyone would laugh and roll their eyes at me for being 22, and graduated highschool and not having the slightest idea how to solve any of these math problems. I am over here in tears cause I cant figure out fractions adn basic algebra. How the hell am I ever going to pass a test when I cant even begin to know this ****. It has been like 8 yrs since I have even seen this stuff and hell I barely passed it then...
1 2/3 + 2 1/2- =

2 5/8 - 2 5/16=

12/5 divided by 7/12=

12z - 3 (z-6)

(x-2)(x-8) don' t the parenthesis mean you opposite it like remove them and turn the plus to a minus? that was my out on a limb trying to remember....

12a to the 3rd power - 6a divided by 3a

I mean I look at this stuff and it looks like something a 8th grader does but I don't get it! I don't know how to ask for help online here but no one in this house remembers or has seen it... hell my dad is 64 he doesn't know jack about this crap....
Thanks for any help... it means so much

good luck. I think I got one of the problems but I wouldn't count on it. I suck at fractions and basic algebra

Ok for the first two cori, the first thing you want to do is make them into whole fractions, second you want to make those fractions have a common denominator.
Example: the first one

*to make 1 2/3 into a whole fraction, first multiply to whole number by the denominator, which makes 3, then add the numerator, that makes 5, so your whole fraction would be 5/3, now do the same to the second number.

*next you want to give them common denominators....

Ok I'll be back, watching LOST, waiting for a commercial

Thanks Renee... I will work on that one while you watching your show!

My math skills say the answer is 1/2 but we will see what Renee says since I suck at math

sdshorty · 02-09-2006, 12:23 AM

Ok so then the first one will be 5/3 and the second 5/2, so in order to give them a common denominator, the easiest way is to find the first number they both have in common, or that they are both divisible by. In this case, both 2 and 3 have the number 6 in common, 6 is divisible by both 2 and 3.

*for 5/3, in order to make the denominator a 6, you have to multiply the 3 by 2, however, whatever you do to the denominator you must do to the numerator. So you have to multiply both the 5 and the 3 by 2. This will give you a fraction of 10/6.

Now do the same to the next fraction.

*for 5/2, you have to multiply 2 by 3 in order to make it 6, so do the same to the 5. That makes it 15/6

So here is your final sentence:

10/6 + 15/6

OK BRB again, LOL

with the fractions you just find a common denominator - eg 2 5/8 - 2 5/16 can be written as 2 10/16 - 2 5/16. Then you just subtract as usual, so the answer would be 5/16

12z - 3(z-6)

12z - 3z - 18

9z - 18

(x-2)(x-8)

xsquared -8x -2x +16

xsquared -10x +16 (I think!)

*~*Cori*~* · 02-09-2006, 12:30 AM

Yea, I have all the answers just have NO idea how to get them

I don't understand this **** for anything.... What do I do with the negatives? Like the 1st question the last fraction is a negative... Oh my god this makes no sense... even reading it, it sounds like a foreign language... what is wrong with me
