56.21 is what percent of 80.3 - 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 80.3 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 80.3, so we can write it down as 100%=80.3.
4. We know, that x% equals 56.21 of the output value, so we can write it down as x%=56.21.
5. Now we have two simple equations:
1) 100%=80.3
2) x%=56.21
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%=80.3/56.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 56.21 is what percent of 80.3

100%/x%=80.3/56.21
(100/x)*x=(80.3/56.21)*x       - we multiply both sides of the equation by x
100=1.4285714285714*x       - we divide both sides of the equation by (1.4285714285714) to get x
100/1.4285714285714=x
70=x
x=70

now we have:
56.21 is 70% of 80.3
