A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.
Given that;
During a test, 3 out of 100 cars selected at random were found to be defective.

Since, During a test, 3 out of 100 cars selected at random were found to be defective.
Let number of defective cars if 1,500 cars are tested = x
So, By definition of ratio, we get;
⇒ 3 / 100 = x / 1,500
Solve for x as;
⇒ 3 × 1500 / 100 = x
⇒ 3 × 15 = x
⇒ x = 45
Thus, There are 45 defective cars if 1,500 cars are tested.
