4.72 is what percent of 149 - 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 149 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 149, so we can write it down as 100%=149.
4. We know, that x% equals 4.72 of the output value, so we can write it down as x%=4.72.
5. Now we have two simple equations:
1) 100%=149
2) x%=4.72
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%=149/4.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.72 is what percent of 149

100%/x%=149/4.72
(100/x)*x=(149/4.72)*x       - we multiply both sides of the equation by x
100=31.567796610169*x       - we divide both sides of the equation by (31.567796610169) to get x
100/31.567796610169=x
3.1677852348993=x
x=3.1677852348993

now we have:
4.72 is 3.1677852348993% of 149
