u can divide 50 by 1000
To find the percentage you have to divide the part over the whole then multiply by 1000, in this example we want to find out the percentage corresponding to the defective pens.
No. Defective pens= 50
No. Pens = 1000
^ this means all pens defective and none defective since we went to see what proportion they make out of the WHOLE

part / whole *100= defective pens%

50/1000 * 100 = defective pens%
Defective pens = 5%

So, 5% of all pens in that factory are defective.
