What is 67.9 percent of 126 - 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 126 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 126 is 100%, so we can write it down as 126=100%.
4. We know, that x is 67.9% of the output value, so we can write it down as x=67.9%.
5. Now we have two simple equations:
1) 126=100%
2) x=67.9%
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:
126/x=100%/67.9%
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 67.9% of 126

126/x=100/67.9
(126/x)*x=(100/67.9)*x       - we multiply both sides of the equation by x
126=1.4727540500736*x       - we divide both sides of the equation by (1.4727540500736) to get x
126/1.4727540500736=x
85.554=x
x=85.554

now we have:
67.9% of 126=85.554
