Question

If a car factory checks 380 cars and 11 of them havedefects, how many will have defects out of 1260 cars?

Answer 1

Step-by-step explanation:

Let x represent the number of defective cars.

Assuming that number of defective cars are uniformly distributed in the total number of cars, we can go ahead and solve for x by setting up proportion as shown below;

`\begin{gathered} (11)/(380)=(x)/(1260) \\ 380x=13860 \\ x=(13860)/(380) \\ x=40 \end{gathered}`
