What is 4.89 percent of 770 - 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 770 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 770 is 100%, so we can write it down as 770=100%.
4. We know, that x is 4.89% of the output value, so we can write it down as x=4.89%.
5. Now we have two simple equations:
1) 770=100%
2) x=4.89%
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:
770/x=100%/4.89%
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 4.89% of 770

770/x=100/4.89
(770/x)*x=(100/4.89)*x       - we multiply both sides of the equation by x
770=20.449897750511*x       - we divide both sides of the equation by (20.449897750511) to get x
770/20.449897750511=x
37.653=x
x=37.653

now we have:
4.89% of 770=37.653
