4 over 9 divided by 2

Strike441 [17]

Answer:

$\frac{4}{9}\div 2=\frac{2}{9}$

Step-by-step explanation:

We want to simplify;

$\frac{4}{9}\div 2$

We can rewrite to get;

$\frac{4}{9}\div \frac{2}{1}$

We multiply the first fraction by the multiplicative inverse of the second fraction to get;

$\frac{4}{9}\times \frac{1}{2}$

This gives us;

$\frac{4\times1}{9\times2}$

Simplify to get;

$\frac{2\times1}{9\times1}$

Multiply;

$=\frac{2}{9}$
