Answer:
0.4032
Step-by-step explanation:
1. We assume, that the number <em>72 is 100%</em> - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If <em>72 is 100%</em>, so we can write it down as <em>72=100%</em>.
4. We know, that x is <em>0.56%</em> of the output value, so we can write it down as <em>x=0.56%</em>.
5. Now we have two simple equations:
1) <em>72=100%</em>
2) <em>x=0.56%</em>
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:
<em>72/x=100%/0.56%</em>
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
