What is 3 percent of 102890 - 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 102890 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 102890 is 100%, so we can write it down as 102890=100%.
4. We know, that x is 3% of the output value, so we can write it down as x=3%.
5. Now we have two simple equations:
1) 102890=100%
2) x=3%
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:
102890/x=100%/3%
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 3% of 102890

102890/x=100/3
(102890/x)*x=(100/3)*x       - we multiply both sides of the equation by x
102890=33.333333333333*x       - we divide both sides of the equation by (33.333333333333) to get x
102890/33.333333333333=x
3086.7=x
x=3086.7

now we have:
3% of 102890=3086.7
