7.84 is what percent of 45.31 - 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 45.31 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 45.31, so we can write it down as 100%=45.31.
4. We know, that x% equals 7.84 of the output value, so we can write it down as x%=7.84.
5. Now we have two simple equations:
1) 100%=45.31
2) x%=7.84
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%=45.31/7.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.84 is what percent of 45.31

100%/x%=45.31/7.84
(100/x)*x=(45.31/7.84)*x       - we multiply both sides of the equation by x
100=5.7793367346939*x       - we divide both sides of the equation by (5.7793367346939) to get x
100/5.7793367346939=x
17.303023615096=x
x=17.303023615096

now we have:
7.84 is 17.303023615096% of 45.31
