35 is what percent of 51.2 - 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 51.2 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 51.2, so we can write it down as 100%=51.2.
4. We know, that x% equals 35 of the output value, so we can write it down as x%=35.
5. Now we have two simple equations:
1) 100%=51.2
2) x%=35
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%=51.2/35
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 35 is what percent of 51.2

100%/x%=51.2/35
(100/x)*x=(51.2/35)*x       - we multiply both sides of the equation by x
100=1.4628571428571*x       - we divide both sides of the equation by (1.4628571428571) to get x
100/1.4628571428571=x
68.359375=x
x=68.359375

now we have:
35 is 68.359375% of 51.2
