21.8 is what percent of 1.77 - 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 1.77 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 1.77, so we can write it down as 100%=1.77.
4. We know, that x% equals 21.8 of the output value, so we can write it down as x%=21.8.
5. Now we have two simple equations:
1) 100%=1.77
2) x%=21.8
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%=1.77/21.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.8 is what percent of 1.77

100%/x%=1.77/21.8
(100/x)*x=(1.77/21.8)*x       - we multiply both sides of the equation by x
100=0.081192660550459*x       - we divide both sides of the equation by (0.081192660550459) to get x
100/0.081192660550459=x
1231.6384180791=x
x=1231.6384180791

now we have:
21.8 is 1231.6384180791% of 1.77
