The correct Answer is:
To solve the question "2 is 10% of what number?", we can follow these steps: ### Step 1: Define the unknown Let’s denote the unknown number as \( X \). **Hint:** When dealing with percentages, it's helpful to define the unknown variable clearly. ### Step 2: Write the percentage equation Since we know that 10% of \( X \) is equal to 2, we can express this mathematically as: \[ 10\% \text{ of } X = 2 \] This can be rewritten as: \[ \frac{10}{100} \times X = 2 \] **Hint:** Remember that "percent" means "per hundred," so 10% can be converted to a fraction. ### Step 3: Simplify the equation We can simplify \( \frac{10}{100} \) to \( \frac{1}{10} \): \[ \frac{1}{10} \times X = 2 \] **Hint:** Simplifying fractions can make calculations easier. ### Step 4: Solve for \( X \) To isolate \( X \), multiply both sides of the equation by 10: \[ X = 2 \times 10 \] \[ X = 20 \] **Hint:** When you want to isolate a variable, perform the same operation on both sides of the equation. ### Conclusion Thus, the number \( X \) is 20. Therefore, 2 is 10% of 20. **Final Answer:** \( X = 20 \) ---
