as 100%=45.

4. We know, that x% equals 4.5 of the output value, so we can write it down as x%=4.5.

5. Now we have two simple equations:

1) 100%=45

2) x%=4.5

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%=45/4.5

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.5 is what percent of 45

100%/x%=45/4.5

(100/x)*x=(45/4.5)*x - we multiply both sides of the equation by x

100=10*x - we divide both sides of the equation by (10) to get x

100/10=x

10=x

x=10

now we have:

4.5 is 10% of 45
