Question

1 in an automobile parts factory, for every 175 carburetors, 3 are found to be defective. at that rate how many carburetors out of 1,050 could be expected to be defective?

Explanation:

Step1: Calculate the ratio multiplier

Find how many times $175$ fits into $1050$.
$$\frac{1050}{175}=6$$

Step2: Find the number of defective carburetors

Multiply the number of defective carburetors in the original ratio by the multiplier.
Since for $175$ carburetors, $3$ are defective, for $1050$ carburetors, the number of defective carburetors is $3\times6 = 18$.

Answer:

$18$
