First, let's remember how we calculate a percentage:
If we call the number "x", 4% is calculated by dividing x by 100 and then multiplying by 4:
![(x)/(100)*4](https://img.qammunity.org/2023/formulas/mathematics/college/g5ckjsekr21wm81jum5cexsk94mmo6wtmc.png)
This can also be represented as follows:
![(4)/(100)* x](https://img.qammunity.org/2023/formulas/mathematics/college/yrbc0dcxk8nqsjiktj74ovethf3wr4t43y.png)
Thus, 4% of a number is 4/100 of that number. We can still simplify this result as follows:
![(4)/(100)=(1)/(25)](https://img.qammunity.org/2023/formulas/mathematics/college/xrrqlz86k4xr8x53o8bo57aptqqwrytzc7.png)
We divide 4 by 4 and get 1, and also divide 100 by 4 and get 25.
Answer: 4% of a number is 1/25 of that number.
