What is 87 percent of 177 - 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 177 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 177 is 100%, so we can write it down as 177=100%.
4. We know, that x is 87% of the output value, so we can write it down as x=87%.
5. Now we have two simple equations:
1) 177=100%
2) x=87%
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:
177/x=100%/87%
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 87% of 177

177/x=100/87
(177/x)*x=(100/87)*x       - we multiply both sides of the equation by x
177=1.1494252873563*x       - we divide both sides of the equation by (1.1494252873563) to get x
177/1.1494252873563=x
153.99=x
x=153.99

now we have:
87% of 177=153.99
