We need to find the percentage of prates own a pet crab
There are 20 prates
4 of them own pet
Then we need the percent of 4 out of 20
We will divide 4 by 20 and multiply the answer by 100%
[tex]\frac{4}{20}\times100[/tex]We will simplify it
[tex]\frac{1}{5}\times100=20[/tex]The percentage of prates on the ship own a pet is 20%
