What is 1.3 percent of 17.8 - 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 17.8 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 17.8 is 100%, so we can write it down as 17.8=100%.
4. We know, that x is 1.3% of the output value, so we can write it down as x=1.3%.
5. Now we have two simple equations:
1) 17.8=100%
2) x=1.3%
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:
17.8/x=100%/1.3%
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 1.3% of 17.8

17.8/x=100/1.3
(17.8/x)*x=(100/1.3)*x       - we multiply both sides of the equation by x
17.8=76.923076923077*x       - we divide both sides of the equation by (76.923076923077) to get x
17.8/76.923076923077=x
0.2314=x
x=0.2314

now we have:
1.3% of 17.8=0.2314
