0.4 is what percent of 45.656 - 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 45.656 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 45.656, so we can write it down as 100%=45.656.
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%=45.656
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%=45.656/0.4
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 45.656

100%/x%=45.656/0.4
(100/x)*x=(45.656/0.4)*x       - we multiply both sides of the equation by x
100=114.14*x       - we divide both sides of the equation by (114.14) to get x
100/114.14=x
0.87611704923778=x
x=0.87611704923778

now we have:
0.4 is 0.87611704923778% of 45.656
