The correct Answer is:
To simplify the expression \(70\% \text{ of } 100 \times 12 = ? - 25\), we can follow these steps: ### Step 1: Convert the percentage to a fraction First, we convert \(70\%\) into a fraction: \[ 70\% = \frac{70}{100} \] ### Step 2: Multiply by 100 Now, we calculate \(70\%\) of \(100\): \[ \frac{70}{100} \times 100 \] The \(100\) in the numerator and denominator cancels out: \[ = 70 \] ### Step 3: Multiply by 12 Next, we multiply \(70\) by \(12\): \[ 70 \times 12 \] Calculating this gives: \[ 70 \times 12 = 840 \] ### Step 4: Set up the equation Now we substitute back into the equation: \[ 840 = ? - 25 \] ### Step 5: Solve for the unknown To find the value of \(?\), we add \(25\) to both sides of the equation: \[ 840 + 25 = ? \] Calculating this gives: \[ 865 = ? \] ### Final Answer Thus, the value of \(?\) is: \[ ? = 865 \]
