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

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.

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?

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?

\frac14 + \frac{1}{12}

Convert:

\frac14 = \frac{?}{12}

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! :)

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.

\frac12 = \frac{?}{100}

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

\frac12 \times \frac{50}{50} = \frac{50}{100}

Another one.

\frac{3}{8} = \frac{?}{64}

Multiply by 8/8;

\frac38 \times \frac88 = \frac{24}{64}

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

\frac14 = \frac{?}{12}
