Just multiply them simply. :)

anonymous · Answer

It told me the answer is wrong.  I got -546/11466.  I know I have to make the fraction smaller but I don't even know where to begin with that.

akashdeepdeb · Answer

Haha...No.
Do not multiply everything like that.
Cancel out some terms too! :D

anonymous · Answer

How?  Can you please explain.

akashdeepdeb · Answer

I'll give you a hint.

(216/343) * (49/36)
Answer?

akashdeepdeb · Answer

When you see some terms divisible by some other just simply cancel them out

$$\frac{216}{343} * \frac{49}{36}$$

Now 216 is divisible by 216
And 343 is divisible by 49

Answer: 6/7

Now try doing your question. :)

anonymous · Answer

How did you get 216/343 * 49/36?

akashdeepdeb · Answer

It is an EXAMPLE

anonymous · Answer

$-\dfrac{7}{3}\times -\dfrac{2}{21} \times -\dfrac{13}{14} \times -\dfrac{3}{13}$
Start by finding a number in the numerator that is the same as a number in the denominator. Cancel that one out.
