21.43 is what percent of 34.21 - 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 34.21 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 34.21, so we can write it down as 100%=34.21.
4. We know, that x% equals 21.43 of the output value, so we can write it down as x%=21.43.
5. Now we have two simple equations:
1) 100%=34.21
2) x%=21.43
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%=34.21/21.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.43 is what percent of 34.21

100%/x%=34.21/21.43
(100/x)*x=(34.21/21.43)*x       - we multiply both sides of the equation by x
100=1.5963602426505*x       - we divide both sides of the equation by (1.5963602426505) to get x
100/1.5963602426505=x
62.642502192341=x
x=62.642502192341

now we have:
21.43 is 62.642502192341% of 34.21
