Now, the equation is

21/2 + 27/4

Here, you can now do the same thing you would do as if it was a regular fraction.

21/2 + 27/4

21/2 x 2 = 42/4

42/4 + 27/4 = 69/4

= 17 1/4

Now, it's time to move on to another subject: multiplying.

Multiplying fractions. It's so easy a chimp could do it. Seriously. You just multiply the numerators by the numerators and the denominators by the denominators. THAT'S IT.

Let's try this example:

2/3 x 9/10

You just have to multiply the two numerators (2 x 9) and the two denominators (3 x 10)

As a result you get:

18/30

Simplified, it is 3/5.

What? Oh, you didn't get it the first time? You want me to do it again? FINE. BUT JUST ONE MORE TIME.

Here's your example:

3/4 x 4/5

Okay, now solve it.

...

...

...

Okay, okay, I'll do the work for you...

3/4 x 4/5

3 x 4 = 12

4 x 5 = 20

Therefore, the answer must be 12/20

Simplified, the answer is 3/5

Now, for a subject that will really make your head hurt: Dividing fractions.

To divide fractions, you have to think in 1 of 2 ways: First, you can try and think "How many groups of (second number) go into (first number)?"

Or you can think paint can vs. room. You have used so much of a paint can to paint so much of your room. This involves taking the easy way out and making a ratio table.

First, the first method.

I'm gonna make this REAL easy.

1 1/2 / 1/2

You just have to find how many groups of 1/2 go into 1 1/2.

SOLVE.

...

...

OKAY, I'LL SOLVE IT FOR YOU, BUT THIS IS THE LAST TIME.

1 1/2 / 1/2YOU HAVE TO FIND HOW MANY GROUPS OF 1/2 GO INTO 1 1/2

To do this, you have to make the mixed number improper.

When you do, the number becomes 3/2.

It becomes THREE HALVES.

You have to find how many groups of ONE HALVE go into THREE HALVES.

If you didn't know, the answer is 3.

Okay, let's try this with another question and method.

3/4 / 1/3.

Let's try this with a ratio table this time.

3/4 1/3*

9/4 3/3 If we multiply by 3*, we can get a whole number.

As we all know, when you divide a number by 1 you get the number.

So the answer is 9/4 or 2 1/4
