1.45 is what percent of 320 - 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 320 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 320, so we can write it down as 100%=320.
4. We know, that x% equals 1.45 of the output value, so we can write it down as x%=1.45.
5. Now we have two simple equations:
1) 100%=320
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:
100%/x%=320/1.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.45 is what percent of 320

100%/x%=320/1.45
(100/x)*x=(320/1.45)*x       - we multiply both sides of the equation by x
100=220.68965517241*x       - we divide both sides of the equation by (220.68965517241) to get x
100/220.68965517241=x
0.453125=x
x=0.453125

now we have:
1.45 is 0.453125% of 320
