1720 is what percent of 1975 - 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 1975 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 1975, so we can write it down as 100%=1975.
4. We know, that x% equals 1720 of the output value, so we can write it down as x%=1720.
5. Now we have two simple equations:
1) 100%=1975
2) x%=1720
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%=1975/1720
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1720 is what percent of 1975

100%/x%=1975/1720
(100/x)*x=(1975/1720)*x       - we multiply both sides of the equation by x
100=1.1482558139535*x       - we divide both sides of the equation by (1.1482558139535) to get x
100/1.1482558139535=x
87.088607594937=x
x=87.088607594937

now we have:
1720 is 87.088607594937% of 1975
