First you want to find your denominator. I believe that is the bottom number.

Do you know how to find that?
anonymous

@rainbow_rocks03 to find the denominator you need to find the least common factor that they share.
rainbow_rocks03
  • rainbow_rocks03
LCF or LDC OR are they the same thing?
anonymous
  • anonymous
LCM. Sorry multiple not factor.
anonymous
  • anonymous
So for 6 and 9 what is the smallest or least common multiple that they share?
rainbow_rocks03
  • rainbow_rocks03
oh, its alright...so the LCM for 6 & 9?
anonymous
  • anonymous
Yes. Do you have an idea what it would be?
rainbow_rocks03
  • rainbow_rocks03
the LCM for 6 & 9 is 18?
anonymous
  • anonymous
Yes. So that is your denominator.
anonymous
  • anonymous
Now for LCF/R and LCF/L
rainbow_rocks03
  • rainbow_rocks03
so now it is 6/18 & 9/18 , right?
anonymous
  • anonymous
No
rainbow_rocks03
  • rainbow_rocks03
oh
anonymous
  • anonymous
You now have ?/18.

rainbow_rocks03
  • rainbow_rocks03
umm...idk
rainbow_rocks03
  • rainbow_rocks03
oh wait!
rainbow_rocks03
  • rainbow_rocks03
15/19 ? or no?
anonymous
  • anonymous
To find the numerator you find the LCF for the Left Denom. and for the R Denom. No
anonymous
  • anonymous
What is the smallest factor for 6? And what is the smallest factor for 9?
rainbow_rocks03
  • rainbow_rocks03
IDK
anonymous
  • anonymous
What are factors for 6?
anonymous
  • anonymous
Like for 10 they are 2 and 5. The smallest would be 2.
rainbow_rocks03
  • rainbow_rocks03
factors of 6 are 2 and 3...so it would be 2?
anonymous
  • anonymous
Yes. Now for 9?
rainbow_rocks03
  • rainbow_rocks03
factors of 9 are 3 and 9 so 3?
anonymous
  • anonymous
hi
anonymous
  • anonymous
Yes. So now you cross multiply. 2•4 3•5 and the you add them together |dw:1444333528189:dw|
anonymous
  • anonymous
(3•5)+(2•4)=? That is the numerator and then you just simplify
rainbow_rocks03
  • rainbow_rocks03
3*5=15 & 2*4=8
rainbow_rocks03
  • rainbow_rocks03
@rottweilerkloey I said if you could PLZ stop saying hi.
anonymous
  • anonymous
Now add 15 and 8
anonymous
  • anonymous
sorry
rainbow_rocks03
  • rainbow_rocks03
it's alright, 15+8=23
anonymous
  • anonymous
Yes now you have 23/18. You can’t have that so you have to simplify. How many times does 18 go into 23?
rainbow_rocks03
  • rainbow_rocks03
umm....idk
anonymous
  • anonymous
1 time. So 23-18=?
rainbow_rocks03
  • rainbow_rocks03
23-18=5

The first one
rainbow_rocks03
  • rainbow_rocks03
so that is my answer?
anonymous
  • anonymous
Yes for the first question that answer is C
rainbow_rocks03
  • rainbow_rocks03
YAY thx, will you help with the second one?
anonymous
  • anonymous
I will and if you don’t mind me asking. What grade are you in?
rainbow_rocks03
  • rainbow_rocks03
I am in 7th, why?
rainbow_rocks03
  • rainbow_rocks03
BTW I love your profile pic!
anonymous
  • anonymous
Just wondering and I’m in 10th. And thanks can never go wrong with the Cheshire Cat
rainbow_rocks03
  • rainbow_rocks03
I love the Cheshire cat!
anonymous
  • anonymous
Okay for the second one you need to find the LCM again
rainbow_rocks03
  • rainbow_rocks03
ok
rainbow_rocks03
  • rainbow_rocks03
but which numbers do I find for the LCM?
anonymous
  • anonymous
The denominators 8 and 12
rainbow_rocks03
  • rainbow_rocks03
so I find the LCM for 8 & 12
anonymous
  • anonymous
Yes
anonymous
  • anonymous
At least this is what I think you do. I haven’t done this since 6th grade. 0_o let me check real quick
rainbow_rocks03
  • rainbow_rocks03
ok
anonymous
  • anonymous
Yes it is
rainbow_rocks03
  • rainbow_rocks03
ok so the LCM of 8 and 12 is 24?
anonymous
  • anonymous
Yes
rainbow_rocks03
  • rainbow_rocks03
so now it is 8/24 & 12/24?
anonymous
  • anonymous
No. You basically of the same thing we did the first time. i have to leave in a few minutes so I’ll try and explain fast why it is A.
rainbow_rocks03
  • rainbow_rocks03
ok
anonymous
  • anonymous
You need to convert the 15 into the fraction and same with the 11. 15•12=180+5=185 185/12 11•8=88+1=89 89/8
rainbow_rocks03
  • rainbow_rocks03
so my answer is 4 7/24 ? thats why?
anonymous
  • anonymous
Kinda
rainbow_rocks03
  • rainbow_rocks03
ok TY!
rainbow_rocks03
  • rainbow_rocks03
or is there still more?
anonymous
  • anonymous
Go to http://www.tiger-algebra.com and enter it and it should explain. I use it for Algebra 2 and it explains everything. I have to go. I’m sorry I couldn’t help much with the second one!
rainbow_rocks03
  • rainbow_rocks03
it's alright TY though!!
rainbow_rocks03
  • rainbow_rocks03
but my answer is the first choice?
