1986 is what percent of 1537 - 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 1537 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 1537, so we can write it down as 100%=1537.
4. We know, that x% equals 1986 of the output value, so we can write it down as x%=1986.
5. Now we have two simple equations:
1) 100%=1537
2) x%=1986
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%=1537/1986
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1986 is what percent of 1537

100%/x%=1537/1986
(100/x)*x=(1537/1986)*x       - we multiply both sides of the equation by x
100=0.77391742195368*x       - we divide both sides of the equation by (0.77391742195368) to get x
100/0.77391742195368=x
129.21275211451=x
x=129.21275211451

now we have:
1986 is 129.21275211451% of 1537
