0.357 is what percent of 7 - 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 7 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 7, so we can write it down as 100%=7.
4. We know, that x% equals 0.357 of the output value, so we can write it down as x%=0.357.
5. Now we have two simple equations:
1) 100%=7
2) x%=0.357
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%=7/0.357
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.357 is what percent of 7

100%/x%=7/0.357
(100/x)*x=(7/0.357)*x       - we multiply both sides of the equation by x
100=19.607843137255*x       - we divide both sides of the equation by (19.607843137255) to get x
100/19.607843137255=x
5.1=x
x=5.1

now we have:
0.357 is 5.1% of 7
