Divide the top and bottom by their highest common factor (HCF).

If you don't know their HCF, or are unsure of dividing by large numbers, divide top and bottom by any common factor and repeat until they have no common factor.

That's how to simplify 8/28, this is it being done:

8 and 28 have the HCF of 4, therefore:

8/28 = (8÷4)/(28÷4)

= 2/7
