2.2 is what percent of 145 - 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 145 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 145, so we can write it down as 100%=145.
4. We know, that x% equals 2.2 of the output value, so we can write it down as x%=2.2.
5. Now we have two simple equations:
1) 100%=145
2) x%=2.2
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%=145/2.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.2 is what percent of 145

100%/x%=145/2.2
(100/x)*x=(145/2.2)*x       - we multiply both sides of the equation by x
100=65.909090909091*x       - we divide both sides of the equation by (65.909090909091) to get x
100/65.909090909091=x
1.5172413793103=x
x=1.5172413793103

now we have:
2.2 is 1.5172413793103% of 145
