One friend would get 1 whole and then you would have to split the 3 in half and give that to your friends. So they each get 1 1/2.
<span>16/20 is 80%.</span>
You find out by multiplying the denominator: 20 * 5 = 100
Then, you do the same to the numerator which is: 16 * 5 = x
So, x = 80%
Hope this helps! :D
