What is 68.7 percent of 72 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 72 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 72 is 100%, so we can write it down as 72=100%.
4. We know, that x is 68.7% of the output value, so we can write it down as x=68.7%.
5. Now we have two simple equations:
1) 72=100%
2) x=68.7%
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:
72/x=100%/68.7%
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 68.7% of 72

72/x=100/68.7
(72/x)*x=(100/68.7)*x       - we multiply both sides of the equation by x
72=1.4556040756914*x       - we divide both sides of the equation by (1.4556040756914) to get x
72/1.4556040756914=x
49.464=x
x=49.464

now we have:
68.7% of 72=49.464
