What is 34 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 1221 is 100%, so we can write it down as 1221=100%.
4. We know, that x is 34% of the output value, so we can write it down as x=34%.
5. Now we have two simple equations:
1) 1221=100%
2) x=34%
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:
1221/x=100%/34%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 34% of 1221

1221/x=100/34
(1221/x)*x=(100/34)*x       - we multiply both sides of the equation by x
1221=2.9411764705882*x       - we divide both sides of the equation by (2.9411764705882) to get x
1221/2.9411764705882=x
415.14=x
x=415.14

now we have:
34% of 1221=415.14
