68. 7 out of 8 students were surveyed to have their owned bike. Now, let’s solve for the value of the number of students who owned a bike if the number of who does not owned is 72. => the ratio is 7 : 8 Now, the formula would be like this: => 7 : 8 = x : 72 => First multiply the outer value => 7 * 72 = 504 => Next, divide the product with the innerr value => 504 / 8 = 63 Thus, the value of the students who owned a bike is 63.
Seven out of every 8 students surveyed owns a bike. The difference between the number of students who own a bike and those who do not is 72. How many students were surveyed?
