What is 1.3 percent of 7.999 - 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 7.999 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 7.999 is 100%, so we can write it down as 7.999=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) 7.999=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:
7.999/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 7.999

7.999/x=100/1.3
(7.999/x)*x=(100/1.3)*x       - we multiply both sides of the equation by x
7.999=76.923076923077*x       - we divide both sides of the equation by (76.923076923077) to get x
7.999/76.923076923077=x
0.103987=x
x=0.103987

now we have:
1.3% of 7.999=0.103987
