35.4 is what percent of 43.7 - 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 43.7 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 43.7, so we can write it down as 100%=43.7.
4. We know, that x% equals 35.4 of the output value, so we can write it down as x%=35.4.
5. Now we have two simple equations:
1) 100%=43.7
2) x%=35.4
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%=43.7/35.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 35.4 is what percent of 43.7

100%/x%=43.7/35.4
(100/x)*x=(43.7/35.4)*x       - we multiply both sides of the equation by x
100=1.2344632768362*x       - we divide both sides of the equation by (1.2344632768362) to get x
100/1.2344632768362=x
81.006864988558=x
x=81.006864988558

now we have:
35.4 is 81.006864988558% of 43.7
