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.
