To write a fraction in simplest form you need to identify common factors between the numerator and denominator. In this case, both numbers are even, so clearly have a common factor of 2. We can therefore divide both top and bottom by 2:
62/2=31
72/2=36
This leaves us with the fraction 31/36. As 31 is a Prime number, this fraction cannot be simplified any further, which means that 31/36 is the simplest form.
206/72 as a mixed number is 2 and 62/72 or 2 and 31/36 in its simplest form
