21.4 is what percent of 29.3 - 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 29.3 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 29.3, so we can write it down as 100%=29.3.
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%=29.3
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%=29.3/21.4
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 29.3

100%/x%=29.3/21.4
(100/x)*x=(29.3/21.4)*x       - we multiply both sides of the equation by x
100=1.3691588785047*x       - we divide both sides of the equation by (1.3691588785047) to get x
100/1.3691588785047=x
73.037542662116=x
x=73.037542662116

now we have:
21.4 is 73.037542662116% of 29.3
