1.29 is what percent of 27 - 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 27 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 27, so we can write it down as 100%=27.
4. We know, that x% equals 1.29 of the output value, so we can write it down as x%=1.29.
5. Now we have two simple equations:
1) 100%=27
2) x%=1.29
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%=27/1.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.29 is what percent of 27

100%/x%=27/1.29
(100/x)*x=(27/1.29)*x       - we multiply both sides of the equation by x
100=20.93023255814*x       - we divide both sides of the equation by (20.93023255814) to get x
100/20.93023255814=x
4.7777777777778=x
x=4.7777777777778

now we have:
1.29 is 4.7777777777778% of 27
