What is 1210 percent of 45 - 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 45 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 45 is 100%, so we can write it down as 45=100%.
4. We know, that x is 1210% of the output value, so we can write it down as x=1210%.
5. Now we have two simple equations:
1) 45=100%
2) x=1210%
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:
45/x=100%/1210%
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 1210% of 45

45/x=100/1210
(45/x)*x=(100/1210)*x       - we multiply both sides of the equation by x
45=0.082644628099174*x       - we divide both sides of the equation by (0.082644628099174) to get x
45/0.082644628099174=x
544.5=x
x=544.5

now we have:
1210% of 45=544.5
