What is 138.5 percent of 170 - 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 170 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 170 is 100%, so we can write it down as 170=100%.
4. We know, that x is 138.5% of the output value, so we can write it down as x=138.5%.
5. Now we have two simple equations:
1) 170=100%
2) x=138.5%
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:
170/x=100%/138.5%
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 138.5% of 170

170/x=100/138.5
(170/x)*x=(100/138.5)*x       - we multiply both sides of the equation by x
170=0.72202166064982*x       - we divide both sides of the equation by (0.72202166064982) to get x
170/0.72202166064982=x
235.45=x
x=235.45

now we have:
138.5% of 170=235.45
