38.3 is what percent of 170.5 - 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 170.5 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 170.5, so we can write it down as 100%=170.5.
4. We know, that x% equals 38.3 of the output value, so we can write it down as x%=38.3.
5. Now we have two simple equations:
1) 100%=170.5
2) x%=38.3
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%=170.5/38.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.3 is what percent of 170.5

100%/x%=170.5/38.3
(100/x)*x=(170.5/38.3)*x       - we multiply both sides of the equation by x
100=4.4516971279373*x       - we divide both sides of the equation by (4.4516971279373) to get x
100/4.4516971279373=x
22.463343108504=x
x=22.463343108504

now we have:
38.3 is 22.463343108504% of 170.5
