1.64 is what percent of 2.04 - 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 2.04 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 2.04, so we can write it down as 100%=2.04.
4. We know, that x% equals 1.64 of the output value, so we can write it down as x%=1.64.
5. Now we have two simple equations:
1) 100%=2.04
2) x%=1.64
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%=2.04/1.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.64 is what percent of 2.04

100%/x%=2.04/1.64
(100/x)*x=(2.04/1.64)*x       - we multiply both sides of the equation by x
100=1.2439024390244*x       - we divide both sides of the equation by (1.2439024390244) to get x
100/1.2439024390244=x
80.392156862745=x
x=80.392156862745

now we have:
1.64 is 80.392156862745% of 2.04
