1. We assume, that the number 0.7 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 0.7 is 100%, so we can write it down as 0.7=100%. 4. We know, that x is 0.33% of the output value, so we can write it down as x=0.33%. 5. Now we have two simple equations: 1) 0.7=100% 2) x=0.33% 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: 0.7/x=100%/0.33% 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 0.33% of 0.7
0.7/x=100/0.33 (0.7/x)*x=(100/0.33)*x - we multiply both sides of the equation by x 0.7=303.0303030303*x - we divide both sides of the equation by (303.0303030303) to get x 0.7/303.0303030303=x 0.00231=x x=0.00231
