0.26 is what percent of 1.29 - 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 1.29 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 1.29, so we can write it down as 100%=1.29.
4. We know, that x% equals 0.26 of the output value, so we can write it down as x%=0.26.
5. Now we have two simple equations:
1) 100%=1.29
2) x%=0.26
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%=1.29/0.26
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.26 is what percent of 1.29

100%/x%=1.29/0.26
(100/x)*x=(1.29/0.26)*x       - we multiply both sides of the equation by x
100=4.9615384615385*x       - we divide both sides of the equation by (4.9615384615385) to get x
100/4.9615384615385=x
20.15503875969=x
x=20.15503875969

now we have:
0.26 is 20.15503875969% of 1.29
