Answer:
5% of 20 = 1
Explanation:
Step 1: Our output value is 20.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 20=100%.
Step 4: Similarly, x=5%.
Step 5: This results in a pair of simple equations:
20=100%(1).
x=5%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the right hand side of both equations have the same unit (%); we have
20/x = 100%/5%
Step 7: Again, the reciprocal of both sides gives
x/20 = 5/100 ---> 1
Therefore, 5% of 20 is 1.
