0.8 is what percent of 721423 - 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 721423 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 721423, so we can write it down as 100%=721423.
4. We know, that x% equals 0.8 of the output value, so we can write it down as x%=0.8.
5. Now we have two simple equations:
1) 100%=721423
2) x%=0.8
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%=721423/0.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.8 is what percent of 721423

100%/x%=721423/0.8
(100/x)*x=(721423/0.8)*x       - we multiply both sides of the equation by x
100=901778.75*x       - we divide both sides of the equation by (901778.75) to get x
100/901778.75=x
0.00011089194550215=x
x=0.00011089194550215

now we have:
0.8 is 0.00011089194550215% of 721423
