The correct Answer is:
To find the number for which 16% equals 60, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Problem**: We need to find a number \( x \) such that 16% of \( x \) equals 60. 2. **Set Up the Equation**: We can express 16% as a fraction: \[ 16\% = \frac{16}{100} \] Therefore, we can write the equation: \[ \frac{16}{100} \times x = 60 \] 3. **Simplify the Fraction**: To make calculations easier, we can simplify \( \frac{16}{100} \): \[ \frac{16}{100} = \frac{4}{25} \] Now, substitute this back into the equation: \[ \frac{4}{25} \times x = 60 \] 4. **Isolate \( x \)**: To find \( x \), we can multiply both sides of the equation by the reciprocal of \( \frac{4}{25} \), which is \( \frac{25}{4} \): \[ x = 60 \times \frac{25}{4} \] 5. **Calculate \( x \)**: Now, perform the multiplication: \[ x = 60 \times \frac{25}{4} = \frac{60 \times 25}{4} \] First, calculate \( 60 \times 25 \): \[ 60 \times 25 = 1500 \] Now divide by 4: \[ x = \frac{1500}{4} = 375 \] 6. **Final Answer**: Therefore, the number is: \[ x = 375 \]
