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 %
