51 is what percent of 147 - 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 147 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 147, so we can write it down as 100%=147.
4. We know, that x% equals 51 of the output value, so we can write it down as x%=51.
5. Now we have two simple equations:
1) 100%=147
2) x%=51
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%=147/51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51 is what percent of 147

100%/x%=147/51
(100/x)*x=(147/51)*x       - we multiply both sides of the equation by x
100=2.8823529411765*x       - we divide both sides of the equation by (2.8823529411765) to get x
100/2.8823529411765=x
34.69387755102=x
x=34.69387755102

now we have:
51 is 34.69387755102% of 147
