43 is what percent of 445 - 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 445 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 445, so we can write it down as 100%=445.
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%=445
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%=445/43
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 445

100%/x%=445/43
(100/x)*x=(445/43)*x       - we multiply both sides of the equation by x
100=10.348837209302*x       - we divide both sides of the equation by (10.348837209302) to get x
100/10.348837209302=x
9.6629213483146=x
x=9.6629213483146

now we have:
43 is 9.6629213483146% of 445
