83.98 is what percent of 138 - 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 138 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 100% equals 138, so we can write it down as 100%=138.
4. We know, that x% equals 83.98 of the output value, so we can write it down as x%=83.98.
5. Now we have two simple equations:
1) 100%=138
2) x%=83.98
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:
100%/x%=138/83.98
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 83.98 is what percent of 138

100%/x%=138/83.98
(100/x)*x=(138/83.98)*x       - we multiply both sides of the equation by x
100=1.6432483924744*x       - we divide both sides of the equation by (1.6432483924744) to get x
100/1.6432483924744=x
60.855072463768=x
x=60.855072463768

now we have:
83.98 is 60.855072463768% of 138
