For example: (2/3) / (4/9) will then be written as... (2/3) / (9/4) You then multiply both the numerators and both the denominators 2*9=18 3*4=12 and you get the answer: 18/12 which can simplify down to 3/2 or 1 and 1/2 hope i helped Ps it doesn't matter which fraction you flip as long as its only one that you do flip.<br><b>References : </b><br>The British school system :P Without any explanation of theory the best way I find to do it is to flip one of the fractions and multiply them together.

3*4=12
and you get the answer:
18/12
which can simplify down to
3/2 or 1 and 1/2

hope i helped

Ps it doesn’t matter which fraction you flip as long as its only one that you do flip.

So this problem is 1/2 times 3/2, multiply numerators (top number) and denominators (bottom number) and get 3/4. If you are in high school, ask your math teacher to show you some examples.<br><b>References : </b><br> I am not sure what you mean exactly, but if you mean for example 1/2 divided by 2/3, then the rule is to divide by a fraction, multiply by its reciprocal (the fraction flipped over.)
