I am putting the questions down
First you want to find your denominator. I believe that is the bottom number.
Do you know how to find that?
@rainbow_rocks03 to find the denominator you need to find the least common factor that they share.
LCF or LDC OR are they the same thing?
LCM. Sorry multiple not factor.
So for 6 and 9 what is the smallest or least common multiple that they share?
oh, its alright...so the LCM for 6 & 9?
Yes. Do you have an idea what it would be?
the LCM for 6 & 9 is 18?
Yes. So that is your denominator.
Now for LCF/R and LCF/L
so now it is 6/18 & 9/18 , right?
You now have ?/18.
@haleyelizabeth2017 @kimbllse777 @A.S.L.
15/19 ? or no?
To find the numerator you find the LCF for the Left Denom. and for the R Denom. No
What is the smallest factor for 6? And what is the smallest factor for 9?
What are factors for 6?
Like for 10 they are 2 and 5. The smallest would be 2.
factors of 6 are 2 and 3...so it would be 2?
Yes. Now for 9?
factors of 9 are 3 and 9 so 3?
Yes. So now you cross multiply. 2•4 3•5 and the you add them together |dw:1444333528189:dw|
(3•5)+(2•4)=? That is the numerator and then you just simplify
3*5=15 & 2*4=8
@rottweilerkloey I said if you could PLZ stop saying hi.
Now add 15 and 8
it's alright, 15+8=23
Yes now you have 23/18. You can’t have that so you have to simplify. How many times does 18 go into 23?
1 time. So 23-18=?
The first one
so that is my answer?
Yes for the first question that answer is C
YAY thx, will you help with the second one?
I will and if you don’t mind me asking. What grade are you in?
I am in 7th, why?
BTW I love your profile pic!
Just wondering and I’m in 10th. And thanks can never go wrong with the Cheshire Cat
I love the Cheshire cat!
Okay for the second one you need to find the LCM again
but which numbers do I find for the LCM?
The denominators 8 and 12
so I find the LCM for 8 & 12
At least this is what I think you do. I haven’t done this since 6th grade. 0_o let me check real quick
Yes it is
ok so the LCM of 8 and 12 is 24?
so now it is 8/24 & 12/24?
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.
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
so my answer is 4 7/24 ? thats why?
or is there still more?
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!
it's alright TY though!!
but my answer is the first choice?
