1 is what percent of 1221 - 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 1221 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 1221, so we can write it down as 100%=1221.
4. We know, that x% equals 1 of the output value, so we can write it down as x%=1.
5. Now we have two simple equations:
1) 100%=1221
2) x%=1
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%=1221/1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1 is what percent of 1221

100%/x%=1221/1
(100/x)*x=(1221/1)*x       - we multiply both sides of the equation by x
100=1221*x       - we divide both sides of the equation by (1221) to get x
100/1221=x
0.081900081900082=x
x=0.081900081900082

now we have:
1 is 0.081900081900082% of 1221
