To simplify a fraction, find a number that is divisible evenly by both the numerator (top) and denominator (bottom).
You could start with 2. 20 divided by 2 = 10. 25 divided by 2 = XXXX not a whole number.
3? nope. not whole numbers. 4? nope. not a whole number for 25. 5?
20/5=4
25/5=5
So, the simplified fraction is 4/5.
To check if it can be simplified anymore, look if the numerator and denominator have any of the same multiples.
In this casethey do not, so 4/5 is in simplest form
