Answer: 16.07%
Explanation:
Step 1: We make the assumption that 56 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100% = 56.
Step 4: In the same vein, x%=9.
Step 5: This gives us a pair of simple equations:
100=56(1).
x%=9(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% = 56
--------- ----
x% 9
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% = 9
----- ----
100% 56
x = 16.07%
Therefore, 9 is 16.07% of $56.
