did I do this adding fraction right??
like 1/4+1/12=2/24 ?
is that the right answer?

No. First you have to change 1/4 to something/12. What would that fraction be?

How? To change that

Is it 16/48?

You have to make your denominators the same. That means 1/4 has to equal something/12.

1/4 = ?/12

Let's say the problem is this --

1/2 + 1/8 = ?
1/2 is the same as 4/8
Therefore, the "new" problem is --
4/8 + 1/8 = ?
4/8 + 1/8 = 5/8

1/4 + 1/12 = ?
1/4 is the same as ?/12.

8/12?

No.

4 times ? = 12

wait hold on

I thought your suppose to
1/4+1/12

find the common denominator for the bottoms.

LCD
4:4,8,12,16,20,24,28,32
12:24,36,48,60,72,84,96

well no common ones in there tried the lcd

now if a person found a common denominator

they would
1x12=12
_
4x12=48

1x4=4
_
12x4=48
has to be 16/48?

OK I just want to learn this adding fractoions so I can move on to
Adding mixed numbers

I've been on this adding fractions

For 6 days now
Its reall starting to bug me:mad::mad::mad::mad::mad:

Reduce 16/48.

1/4 + ?/12
Look at the denominators. Now, look at the larger one. Do you see any relation between 4 and 12?

Lcd
4:4,8,12,16,20,24,28,32
12:12,24,36,48,60,72,84,96

Why can't fractions be one step??

Do you know your times tables?

Convert:



What by what do you need to multiply 4 to get 12?
Multiply the numerator of 1/4 by that number to get the ? In ?/12.

Post what you get! :)

Still no help ill try to watch a tutorial video

What times 4 equals 12?

Please answer.

I was thinking maybe a more visual way would be better... =/

Okay, let's take side examples then.



You have to multiply the 2 by 50 to get 100. So, multiply the 1 by 50 too, to get:



Another one.



Multiply by 8/8;



Now, do the same with your fraction and post what you get with
