What is 23 percent of 15.7 - 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 15.7 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 15.7 is 100%, so we can write it down as 15.7=100%.
4. We know, that x is 23% of the output value, so we can write it down as x=23%.
5. Now we have two simple equations:
1) 15.7=100%
2) x=23%
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:
15.7/x=100%/23%
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 23% of 15.7

15.7/x=100/23
(15.7/x)*x=(100/23)*x       - we multiply both sides of the equation by x
15.7=4.3478260869565*x       - we divide both sides of the equation by (4.3478260869565) to get x
15.7/4.3478260869565=x
3.611=x
x=3.611

now we have:
23% of 15.7=3.611
