0.84 is what percent of 87 - 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 87 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 87, so we can write it down as 100%=87.
4. We know, that x% equals 0.84 of the output value, so we can write it down as x%=0.84.
5. Now we have two simple equations:
1) 100%=87
2) x%=0.84
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%=87/0.84
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.84 is what percent of 87

100%/x%=87/0.84
(100/x)*x=(87/0.84)*x       - we multiply both sides of the equation by x
100=103.57142857143*x       - we divide both sides of the equation by (103.57142857143) to get x
100/103.57142857143=x
0.96551724137931=x
x=0.96551724137931

now we have:
0.84 is 0.96551724137931% of 87
