What is 17.9 percent of 124 - 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 124 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 124 is 100%, so we can write it down as 124=100%.
4. We know, that x is 17.9% of the output value, so we can write it down as x=17.9%.
5. Now we have two simple equations:
1) 124=100%
2) x=17.9%
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:
124/x=100%/17.9%
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 17.9% of 124

124/x=100/17.9
(124/x)*x=(100/17.9)*x       - we multiply both sides of the equation by x
124=5.586592178771*x       - we divide both sides of the equation by (5.586592178771) to get x
124/5.586592178771=x
22.196=x
x=22.196

now we have:
17.9% of 124=22.196
