To turn
to a decimal, you must first convert it to an improper fraction, to do that you multiply the whole number (3) and the denominator (4).

Then you add the product of 3 and 4 (12) to the numerator (3).

You then make the sum of the numerator and the product of the whole number and denominator into the numerator.
This leaves us with :

Hope this helped you!
