Question

anonymous · Answer

Have you ever heard of the rule keep it switch it flip it?

mathstudent55 · Answer

To divide a fraction by a fraction:
Copy the first fraction as it is.
Change the division to a multiplication.
Flip the second fraction.
Then multiply the fractions.

Example:

$\dfrac{3}{5} \div \dfrac{7}{8} = \dfrac{3}{5} \color{red}\times \color{green}{\dfrac{8}{7}} $

$= \dfrac{3 \times 8}{5 \times 7}  = \dfrac{24}{35} $

anonymous · Answer

$$\frac{ 2 }{ 3 }\div \frac{ 5 }{ 6 }$$
Multiply by the flipped fraction, simplify if possible.
$$\frac{ 2 }{ 3 }\times \frac{ 6 }{ 5 }=\frac{ 18 }{ 10 }$$
