1.45 is what percent of 1280 - 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 1280 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 1280, so we can write it down as 100%=1280.
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%=1280
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%=1280/1.45
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 1280

100%/x%=1280/1.45
(100/x)*x=(1280/1.45)*x       - we multiply both sides of the equation by x
100=882.75862068966*x       - we divide both sides of the equation by (882.75862068966) to get x
100/882.75862068966=x
0.11328125=x
x=0.11328125

now we have:
1.45 is 0.11328125% of 1280
