Question

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

Answer 1

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 = $560 - 539 = 21$
