47.4 is what percent of 7900 - 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 7900 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 7900, so we can write it down as 100%=7900.
4. We know, that x% equals 47.4 of the output value, so we can write it down as x%=47.4.
5. Now we have two simple equations:
1) 100%=7900
2) x%=47.4
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%=7900/47.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 47.4 is what percent of 7900

100%/x%=7900/47.4
(100/x)*x=(7900/47.4)*x       - we multiply both sides of the equation by x
100=166.66666666667*x       - we divide both sides of the equation by (166.66666666667) to get x
100/166.66666666667=x
0.6=x
x=0.6

now we have:
47.4 is 0.6% of 7900
