Substitute the values into the formula above and simplify.
![=(160)/(4000)*100\text{ }](https://img.qammunity.org/2023/formulas/mathematics/college/oxu0oqnkgju15xf2uzw5bqpiuwz8izmu5y.png)
![=\frac{160}{40\cancel{00}}*1\cancel{00}](https://img.qammunity.org/2023/formulas/mathematics/college/nen4vft8aegvn2aesc6u01jb8488w8f873.png)
![=\frac{16\cancel{0}}{4\cancel{0}}](https://img.qammunity.org/2023/formulas/mathematics/college/o6kcz09tk5n22bmyq6ib80iqy0nq9vd8iy.png)
![=(16)/(4)](https://img.qammunity.org/2023/formulas/mathematics/college/s2gjoxrqugx2z8cmkddfcxez3r1yxyl397.png)
= 4
