16. \( \left(\frac{20}{100}+\frac{25}{100}\right)+\frac{25}{100} \)

To solve the expression: \[ \left(\frac{20}{100} + \frac{25}{100}\right) + \frac{25}{100} \] **Step 1:** Add the fractions inside the first parentheses. \[ \frac{20}{100} + \frac{25}{100} = \frac{20 + 25}{100} = \frac{45}{100} \] **Step 2:** Add the result to the remaining fraction. \[ \frac{45}{100} + \frac{25}{100} = \frac{45 + 25}{100} = \frac{70}{100} \] **Step 3:** Simplify the fraction, if necessary. \[ \frac{70}{100} = 0.70 \quad \text{or} \quad 70\% \] **Final Answer:** The value of the expression is **\(\frac{70}{100}\)**, which is equal to **70%**.
