If a car factory checks 320 cars and 12 of them have defects, how many out of 560 will have defects? Use proportions
Shkiper50 [21]

Answer:

  • Total number of cars having no defection = 539
  • Total number of cars out of 560 will have defects = 560 - 539 = 21

Step-by-step explanation:

As

  • A car factory checks 320 cars, and
  • 12 of them have defects.

Total number of cars = 560

The number of cars defected out of the cars that have

been checked = 320 - 12 = 308

The equation of the scenario will be:

\left[560\:\times \:308\right]\:\div \:320    ⇒    \frac{172480}{320}=539

so

  • Total number of cars having no defection = 539
  • Total number of cars out of 560 will have defects = 560 - 539 = 21
