What is 18.9 percent of 750 - 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 750 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 750 is 100%, so we can write it down as 750=100%.
4. We know, that x is 18.9% of the output value, so we can write it down as x=18.9%.
5. Now we have two simple equations:
1) 750=100%
2) x=18.9%
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:
750/x=100%/18.9%
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 18.9% of 750

750/x=100/18.9
(750/x)*x=(100/18.9)*x       - we multiply both sides of the equation by x
750=5.2910052910053*x       - we divide both sides of the equation by (5.2910052910053) to get x
750/5.2910052910053=x
141.75=x
x=141.75

now we have:
18.9% of 750=141.75
