4.91 is what percent of 159 - 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 159 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 159, so we can write it down as 100%=159.
4. We know, that x% equals 4.91 of the output value, so we can write it down as x%=4.91.
5. Now we have two simple equations:
1) 100%=159
2) x%=4.91
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%=159/4.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.91 is what percent of 159

100%/x%=159/4.91
(100/x)*x=(159/4.91)*x       - we multiply both sides of the equation by x
100=32.382892057026*x       - we divide both sides of the equation by (32.382892057026) to get x
100/32.382892057026=x
3.0880503144654=x
x=3.0880503144654

now we have:
4.91 is 3.0880503144654% of 159
