29 is what percent of 21.51 - 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 21.51 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 21.51, so we can write it down as 100%=21.51.
4. We know, that x% equals 29 of the output value, so we can write it down as x%=29.
5. Now we have two simple equations:
1) 100%=21.51
2) x%=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%=21.51/29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 29 is what percent of 21.51

100%/x%=21.51/29
(100/x)*x=(21.51/29)*x       - we multiply both sides of the equation by x
100=0.74172413793103*x       - we divide both sides of the equation by (0.74172413793103) to get x
100/0.74172413793103=x
134.8210134821=x
x=134.8210134821

now we have:
29 is 134.8210134821% of 21.51
