1. We assume, that the number 110.2 is 100% - because it's the output value of the task. 2. We assume, that x is the value we are looking for. 3. If 110.2 is 100%, so we can write it down as 110.2=100%. 4. We know, that x is 17.7% of the output value, so we can write it down as x=17.7%. 5. Now we have two simple equations: 1) 110.2=100% 2) x=17.7% where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 110.2/x=100%/17.7% 6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 17.7% of 110.2
110.2/x=100/17.7 (110.2/x)*x=(100/17.7)*x - we multiply both sides of the equation by x 110.2=5.64971751412*x - we divide both sides of the equation by (5.64971751412) to get x 110.2/5.64971751412=x 19.5054=x x=19.5054
