Explanation:

Step1: Convert percentage to decimal

To find 15% of 140, first convert 15% to a decimal. We know that \( 15\%=\frac{15}{100} = 0.15\).

Step2: Multiply by total number of students

Now, multiply this decimal by the total number of seventh - grade students (140). So we calculate \(140\times0.15\).
\(140\times0.15=(100 + 40)\times0.15=100\times0.15+40\times0.15 = 15+6=21\).

Answer:
