To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 51 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 51, so we can write it down as 100%=51.
4. We know, that x% equals 127.5 of the output value, so we can write it down as x%=127.5.
5. Now we have two simple equations:
1) 100%=51
2) x%=127.5
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%=51/127.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for...
7. Solution for 127.5 is what percent of 51
100%/x%=51/127.5
(100/x)*x=(51/127.5)*x - we multiply both sides of the equation by x
100=0.4*x - we divide both sides of the equation by (0.4) to get x
100/0.4=x
250=x
x=250
now we have:
127.5 is 250% of 51
