On a factory floor, 30 out of every 140 toy robots is defective. What percent is defective?
yaroslaw [1]

Answer:

21.43\%

Step-by-step explanation:

we know that

To find out the percent of robots which are defective, divided the number of defective robots by the total number of robots and multiply the result by 100

Let

x ----> the number of defective robots

y ----> the total number of robots

p ---> percentage of robots which are defective

so

p=\frac{x}{y} (100)

we have

x=30\\y=140

substitute

p=\frac{30}{140}(100)

p=21.43\%
