What is 13.438 percent of 70 - 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 70 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 70 is 100%, so we can write it down as 70=100%.
4. We know, that x is 13.438% of the output value, so we can write it down as x=13.438%.
5. Now we have two simple equations:
1) 70=100%
2) x=13.438%
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:
70/x=100%/13.438%
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 13.438% of 70

70/x=100/13.438
(70/x)*x=(100/13.438)*x       - we multiply both sides of the equation by x
70=7.4415835689835*x       - we divide both sides of the equation by (7.4415835689835) to get x
70/7.4415835689835=x
9.4066=x
x=9.4066

now we have:
13.438% of 70=9.4066
