21.4 is what percent of 743 - 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 743 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 743, so we can write it down as 100%=743.
4. We know, that x% equals 21.4 of the output value, so we can write it down as x%=21.4.
5. Now we have two simple equations:
1) 100%=743
2) x%=21.4
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%=743/21.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.4 is what percent of 743

100%/x%=743/21.4
(100/x)*x=(743/21.4)*x       - we multiply both sides of the equation by x
100=34.719626168224*x       - we divide both sides of the equation by (34.719626168224) to get x
100/34.719626168224=x
2.8802153432032=x
x=2.8802153432032

now we have:
21.4 is 2.8802153432032% of 743
