Question

If a car factory checks 320 cars and 12 of them have defects, how many out of 560 will NOT have defects?

Answer 1

Answer:

539 cars will not have defects

Step-by-step explanation:

If out of 320 cars, there are 12 cars have defects. That means there are, 320 - 12 = 308 cars that do not have defects out of 320 cars.

If there are 308 cars that do not have defects out of 320 cars. We can set the following equation to calculate the number of cars that will not have defects out of 560 cars.

$\frac{308}{320} = \frac{x}{560}$   From this equation:

→ (308)(560) = (320)(x)

→ x = (308)(560) / 320

→ x = 539
