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
