Answer:

The answer after division is: $2\frac{2}{5}$

Step-by-step explanation:

The given question involves two mixed fractions that are being divided.

$7\frac{1}{2}\div 3\frac{1}{8}$

First of all, we will convert the fractions into proper fractions

$\frac{15}{2}\div \frac{25}{8}$

When the division is performed, the second fraction is reversed

So dividing gives us:

$\frac{15}{2} * \frac{8}{25}\\= \frac{3*4}{5}\\=\frac{12}{5} = 2\frac{2}{5}$

Hence,

The answer after division is: $2\frac{2}{5}$
