1.57 is what percent of 97.9 - 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 97.9 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 97.9, so we can write it down as 100%=97.9.
4. We know, that x% equals 1.57 of the output value, so we can write it down as x%=1.57.
5. Now we have two simple equations:
1) 100%=97.9
2) x%=1.57
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%=97.9/1.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.57 is what percent of 97.9

100%/x%=97.9/1.57
(100/x)*x=(97.9/1.57)*x       - we multiply both sides of the equation by x
100=62.356687898089*x       - we divide both sides of the equation by (62.356687898089) to get x
100/62.356687898089=x
1.6036772216547=x
x=1.6036772216547

now we have:
1.57 is 1.6036772216547% of 97.9
