If you need to know 20% of something, you need to multiply that number by 0.20. Alternatively, you can also divide that number by 5. So 200 times 0.20 = 40 and similarly, 200 / 5 = 40. Multiplying by 0.20 is the same as dividing by 5 so that's why.

The correct answer is 40. This is because 20% is 1/5 so 200 x 1/5= 200/5= 40. Or better yet, 20% is .20 so 200 x .20= 40.00= 40.
