Hey!
Alright, the first step to solving this division problem would be to convert the mixed fraction into a simple fraction. To do that, we'll multiply the denominator by the whole number and then add that total to the numerator.
<em>Original Fraction :</em>

<em>New Fraction {Changed by Conversion} :</em>

Now that we've successfully done that we'll have to change the equation.
<em>Old Equation :</em>

÷

= ?
<em>New Equation {Changed by Flipping the Second Fraction and the Symbol} :</em>

·

= ?
Now we multiply straight across.
<em>Old Equation :</em>

·

= ?
<em>Solved :</em>

Almost done!
Now we have to simplify the fraction.
<em>Old Fraction :</em>

<em>New Fraction {Changed by Simplification} :</em>

Now just convert it to a whole number by removing the fraction line and the number, and that's it!
