Question

On a factory floor, 30 out of every 140 toy robots is defective. What percent of you robots are defective? Round to the nearest hundredth.

Answer 1

30 out of 140
that means the equation is 30/140
that equals .2142 . . .
that moves over the 21%

Answer 2

Answer: 21.43 %

Step-by-step explanation:

Given: On a factory floor, 30 out of every 140 toy robots is defective.

Thus, the total number of robots = 140

The number of defective robots = 30

Now the percent of robots which are defective= $\frac{\text{defective robots}}{\text{total robots}}\times100$

$=\frac{30}{140}\times100$

$=21.42857\%\approx21.43\%$

Hence, the percent  of robots which are defective = 21.43 %
