What is 1.45 percent of 121.75 - 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 121.75 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 121.75 is 100%, so we can write it down as 121.75=100%.
4. We know, that x is 1.45% of the output value, so we can write it down as x=1.45%.
5. Now we have two simple equations:
1) 121.75=100%
2) x=1.45%
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:
121.75/x=100%/1.45%
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 1.45% of 121.75

121.75/x=100/1.45
(121.75/x)*x=(100/1.45)*x       - we multiply both sides of the equation by x
121.75=68.965517241379*x       - we divide both sides of the equation by (68.965517241379) to get x
121.75/68.965517241379=x
1.765375=x
x=1.765375

now we have:
1.45% of 121.75=1.765375
