What is 29.9 percent of 13.4 - 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 13.4 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 13.4 is 100%, so we can write it down as 13.4=100%.
4. We know, that x is 29.9% of the output value, so we can write it down as x=29.9%.
5. Now we have two simple equations:
1) 13.4=100%
2) x=29.9%
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:
13.4/x=100%/29.9%
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 29.9% of 13.4

13.4/x=100/29.9
(13.4/x)*x=(100/29.9)*x       - we multiply both sides of the equation by x
13.4=3.3444816053512*x       - we divide both sides of the equation by (3.3444816053512) to get x
13.4/3.3444816053512=x
4.0066=x
x=4.0066

now we have:
29.9% of 13.4=4.0066
