You can divide each number by 7, so:

28/56 = 4/8, which can be simplified again to 1/2

The ratio shown in fraction form would be; \(\frac{28}{56}\)

Now to convert it to its simplest form, you need to find their greatest common factor; (so in this case it would be 28...cause 28 goes into 56 evenly)
*Now divide both terms by 28

28 ÷ 28 = 1
56 ÷ 28 = 2
 
so your ratio 28 to 56 in simplest form is.. \(\frac{1}{2}\)
Hope this helps :)
