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.

Original Fraction :

3 (3)/(4)

New Fraction {Changed by Conversion} :

(15)/(4)

Now that we've successfully done that we'll have to change the equation.

Old Equation :

(15)/(4) ÷
(2)/(8) = ?

New Equation {Changed by Flipping the Second Fraction and the Symbol} :

(15)/(4) ·
(8)/(2) = ?

Now we multiply straight across.

Old Equation :

(15)/(4) ·
(8)/(2) = ?

Solved :

(120)/(8)

Almost done!
Now we have to simplify the fraction.

Old Fraction :

(120)/(8)

New Fraction {Changed by Simplification} :

(15)/(1)

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

So,
3 (3)/(4) ÷
(2)/(8) equals
15.

Hope this helps!
