0.4 is what percent of 886 - 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 886 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 100% equals 886, so we can write it down as 100%=886.
4. We know, that x% equals 0.4 of the output value, so we can write it down as x%=0.4.
5. Now we have two simple equations:
1) 100%=886
2) x%=0.4
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:
100%/x%=886/0.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.4 is what percent of 886

100%/x%=886/0.4
(100/x)*x=(886/0.4)*x       - we multiply both sides of the equation by x
100=2215*x       - we divide both sides of the equation by (2215) to get x
100/2215=x
0.045146726862302=x
x=0.045146726862302

now we have:
0.4 is 0.045146726862302% of 886
