You can divide a fraction by another fraction in one of two ways:

1) divide the numerator of the quotient by the fraction

2) multiply the fraction by the reciprocal of the divisor fraction.

$\large \sf\color{magenta}{CCFM}$

$\large \sf\color{magenta}C$opy
$\large \sf\color{magenta}C$hange
$\large \sf\color{magenta}F$lip
$\large \sf\color{magenta}M$ultiply

Here is our example problem - $\large\sf\frac{3}{4} ÷ \frac{2}{3}$

$\large\sf\color{magenta}C$ - So first you copy. What it means to copy, is to copy the first fraction down how it is. 

$\large\sf\color{magenta}C$ - Next to change, means to change the division sign into a multiplycation sign like this $\large\sf\frac{3}{4} x \frac{2}{3}$

$\large\sf\color{magenta}F$ - Now what it means to flip, it means to flip the numbers around on the second equation like so - $\large\sf\frac{3}{4} x \frac{2}{3}$ after you flip it looks like this $\large\sf\frac{3}{4} x \frac{3}{2}$. You see how the three and two flipped?

$\large\sf\color{magenta}M$ - What to multiply means is what it means. Now you just multiply your new problem $\large\sf\frac{3}{4} x \frac{3}{2}$ 

Here is the solution to $\large\sf\frac{3}{4} ÷ \frac{2}{3}$ 

Step 1 - $\large\sf\frac{3}{4} ÷ \frac{2}{3}$ 

Step 2 - $\large\sf\frac{3}{4} x \frac{2}{3}$

Step 3 - $\large\sf\frac{3}{4} x \frac{3}{2}$

Step 4 - $\large\sf\frac{3}{4}  \frac{x}{x} \frac{3}{2}=\large\sf\frac{9}{8}$

No problem! My teacher taught me that trick in 6th grade and it SOOO much easier than the other ways to divide fraction :D
