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

LCF or LDC OR are they the same thing?

- anonymous

LCM. Sorry multiple not factor.

- anonymous

So for 6 and 9 what is the smallest or least common multiple that they share?

- rainbow_rocks03

oh, its alright...so the LCM for 6 & 9?

- anonymous

Yes. Do you have an idea what it would be?

- rainbow_rocks03

the LCM for 6 & 9 is 18?

- anonymous

Yes. So that is your denominator.

- anonymous

Now for LCF/R and LCF/L

- rainbow_rocks03

so now it is 6/18 & 9/18 , right?

- anonymous

No

- rainbow_rocks03

oh

- anonymous

You now have ?/18.

- rainbow_rocks03

@haleyelizabeth2017 @kimbllse777 @A.S.L.

- rainbow_rocks03

umm...idk

- rainbow_rocks03

oh wait!

- rainbow_rocks03

15/19 ? or no?

- anonymous

To find the numerator you find the LCF for the Left Denom. and for the R Denom.
No

- anonymous

What is the smallest factor for 6? And what is the smallest factor for 9?

- rainbow_rocks03

IDK

- anonymous

What are factors for 6?

- anonymous

Like for 10 they are 2 and 5. The smallest would be 2.

- rainbow_rocks03

factors of 6 are 2 and 3...so it would be 2?

- anonymous

Yes. Now for 9?

- rainbow_rocks03

factors of 9 are 3 and 9 so 3?

- anonymous

hi

- anonymous

Yes. So now you cross multiply.
2•4
3•5
and the you add them together |dw:1444333528189:dw|

- anonymous

(3•5)+(2•4)=?
That is the numerator and then you just simplify

- rainbow_rocks03

3*5=15 & 2*4=8

- rainbow_rocks03

@rottweilerkloey I said if you could PLZ stop saying hi.

- anonymous

Now add 15 and 8

- anonymous

sorry

- rainbow_rocks03

it's alright, 15+8=23

- 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

umm....idk

- anonymous

1 time. So 23-18=?

- rainbow_rocks03

23-18=5

- anonymous

|dw:1444334066503:dw|

- rainbow_rocks03

|dw:1444334209110:dw|

- anonymous

The first one

- rainbow_rocks03

so that is my answer?

- anonymous

Yes for the first question that answer is C

- rainbow_rocks03

YAY thx, will you help with the second one?

- anonymous

I will
and if you don’t mind me asking. What grade are you in?

- rainbow_rocks03

I am in 7th, why?

- rainbow_rocks03

BTW I love your profile pic!

- anonymous

Just wondering and I’m in 10th. And thanks can never go wrong with the Cheshire Cat

- rainbow_rocks03

I love the Cheshire cat!

- anonymous

Okay for the second one you need to find the LCM again

- rainbow_rocks03

ok

- rainbow_rocks03

but which numbers do I find for the LCM?

- anonymous

The denominators
8 and 12

- rainbow_rocks03

so I find the LCM for 8 & 12

- anonymous

Yes

- 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

ok

- anonymous

Yes it is

- rainbow_rocks03

ok so the LCM of 8 and 12 is 24?

- anonymous

Yes

- rainbow_rocks03

so now it is 8/24 & 12/24?

- 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

ok

- 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

so my answer is 4 7/24 ? thats why?

- anonymous

Kinda

- rainbow_rocks03

ok TY!

- rainbow_rocks03

or is there still more?

- 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

it's alright TY though!!

- rainbow_rocks03

but my answer is the first choice?
