What is 19 percent of 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 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 4 is 100%, so we can write it down as 4=100%.
4. We know, that x is 19% of the output value, so we can write it down as x=19%.
5. Now we have two simple equations:
1) 4=100%
2) x=19%
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:
4/x=100%/19%
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 19% of 4

4/x=100/19
(4/x)*x=(100/19)*x       - we multiply both sides of the equation by x
4=5.26315789474*x       - we divide both sides of the equation by (5.26315789474) to get x
4/5.26315789474=x
0.76=x
x=0.76

now we have:
19% of 4=0.76
