The answer is 0.368
Step 1. Our output value is 80.
Step 2. We need to represent the unknown value with x.
Step 3. From step 1, 80 = 100
Step 4 and Step 5: Similarity x = 0.46% and do 80 = 100% equals to x = 0.46%
Step 6 and step 7: 80/x = 100%/0.46%
Do it again but do it reciprocal of both sides. X/80 = 0.46/100
X=0.368 is the answer
