To find out how to convert mixed numbers to improper you have to do a simple trick. The trick is to multiply the whole number and denominator then add the numerator. If you don’t know what a numerator and denominator is then let me tell you: the numerator is the number on the top of a fraction and the denominator is the bottom of a fraction.
To do the inverse ( improper to mixed numbers) you just have to divide the numerator by the denominator. If there are any remainders then put it as your numerator. e.g. 13/3 – (13 divide 3 =4r1)4 1/3
