To get the answer, you can use cross multiplication:

(20/5%)*(X/100%)

X = (20*100)/5

X = 400

Therefore, 20 is 5% of 400.

Another method you can use is using the formula (Percentage = Base x Rate)

Given: P = 20 ; B = unknown ; R = 5% or 0.05 in decimal

Solution:

20 = B x 0.05

20/0.05 = B

400 = B
