What is 83 percent of 155 - 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 155 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 155 is 100%, so we can write it down as 155=100%.
4. We know, that x is 83% of the output value, so we can write it down as x=83%.
5. Now we have two simple equations:
1) 155=100%
2) x=83%
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:
155/x=100%/83%
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 83% of 155

155/x=100/83
(155/x)*x=(100/83)*x       - we multiply both sides of the equation by x
155=1.2048192771084*x       - we divide both sides of the equation by (1.2048192771084) to get x
155/1.2048192771084=x
128.65=x
x=128.65

now we have:
83% of 155=128.65
