1.59 is what percent of 1.99 - 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 1.99 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 1.99, so we can write it down as 100%=1.99.
4. We know, that x% equals 1.59 of the output value, so we can write it down as x%=1.59.
5. Now we have two simple equations:
1) 100%=1.99
2) x%=1.59
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%=1.99/1.59
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.59 is what percent of 1.99

100%/x%=1.99/1.59
(100/x)*x=(1.99/1.59)*x       - we multiply both sides of the equation by x
100=1.251572327044*x       - we divide both sides of the equation by (1.251572327044) to get x
100/1.251572327044=x
79.899497487437=x
x=79.899497487437

now we have:
1.59 is 79.899497487437% of 1.99
