57/100
The problem would be set up like this... 12 over x = 40 over 100 X represents the percentage we're trying to find, and the 100 below 40 percent represents 100 percent, which is constant among these types of problems. Cross multiply... 40x = 12 * 100 40x = 1200 Divide both sides by 40. x = 30.
11% = 11/100
Think of the following 'sketch' as your 40 boxes... Each X represents one box. Each O represents a shaded box. XXXXXXXXOO XXXXXXXXOO XXXXXXXXXX XXXXXXXXXX
