43 is what percent of 1045 - 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 1045 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 1045, so we can write it down as 100%=1045.
4. We know, that x% equals 43 of the output value, so we can write it down as x%=43.
5. Now we have two simple equations:
1) 100%=1045
2) x%=43
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%=1045/43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43 is what percent of 1045

100%/x%=1045/43
(100/x)*x=(1045/43)*x       - we multiply both sides of the equation by x
100=24.302325581395*x       - we divide both sides of the equation by (24.302325581395) to get x
100/24.302325581395=x
4.1148325358852=x
x=4.1148325358852

now we have:
43 is 4.1148325358852% of 1045
