The correct Answer is:
To solve the problem "If x % of 80 = 12, then x is equal to", we can follow these steps: ### Step 1: Understand the equation We know that x% of 80 is equal to 12. This can be expressed mathematically as: \[ \frac{x}{100} \times 80 = 12 \] ### Step 2: Rewrite the equation We can rewrite the equation to isolate x: \[ 80 \times \frac{x}{100} = 12 \] ### Step 3: Multiply both sides by 100 To eliminate the fraction, we multiply both sides of the equation by 100: \[ 80x = 12 \times 100 \] ### Step 4: Calculate the right side Now, calculate the right side: \[ 80x = 1200 \] ### Step 5: Divide both sides by 80 Next, we divide both sides by 80 to solve for x: \[ x = \frac{1200}{80} \] ### Step 6: Simplify the fraction Now, simplify the fraction: \[ x = 15 \] ### Final Answer Thus, the value of x is: \[ x = 15 \] ---
