155.7 is what percent of 693.7 - 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 693.7 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 693.7, so we can write it down as 100%=693.7.
4. We know, that x% equals 155.7 of the output value, so we can write it down as x%=155.7.
5. Now we have two simple equations:
1) 100%=693.7
2) x%=155.7
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%=693.7/155.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 155.7 is what percent of 693.7

100%/x%=693.7/155.7
(100/x)*x=(693.7/155.7)*x       - we multiply both sides of the equation by x
100=4.4553628773282*x       - we divide both sides of the equation by (4.4553628773282) to get x
100/4.4553628773282=x
22.444860890875=x
x=22.444860890875

now we have:
155.7 is 22.444860890875% of 693.7
