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%
![(4)/(20)*100](https://img.qammunity.org/2023/formulas/mathematics/high-school/f39ysuuwslhfonv7z62gv436lo4vgo8g9u.png)
We will simplify it
![(1)/(5)*100=20](https://img.qammunity.org/2023/formulas/mathematics/high-school/umx22tnyh7om8vqtk0zckkalt8y5rynux3.png)
