34.9 is what percent of 19.9 - 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 19.9 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 19.9, so we can write it down as 100%=19.9.
4. We know, that x% equals 34.9 of the output value, so we can write it down as x%=34.9.
5. Now we have two simple equations:
1) 100%=19.9
2) x%=34.9
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%=19.9/34.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 34.9 is what percent of 19.9

100%/x%=19.9/34.9
(100/x)*x=(19.9/34.9)*x       - we multiply both sides of the equation by x
100=0.5702005730659*x       - we divide both sides of the equation by (0.5702005730659) to get x
100/0.5702005730659=x
175.37688442211=x
x=175.37688442211

now we have:
34.9 is 175.37688442211% of 19.9
