What is 15.4 percent of 69.98 - 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 69.98 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 69.98 is 100%, so we can write it down as 69.98=100%.
4. We know, that x is 15.4% of the output value, so we can write it down as x=15.4%.
5. Now we have two simple equations:
1) 69.98=100%
2) x=15.4%
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:
69.98/x=100%/15.4%
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 15.4% of 69.98

69.98/x=100/15.4
(69.98/x)*x=(100/15.4)*x       - we multiply both sides of the equation by x
69.98=6.4935064935065*x       - we divide both sides of the equation by (6.4935064935065) to get x
69.98/6.4935064935065=x
10.77692=x
x=10.77692

now we have:
15.4% of 69.98=10.77692
