What is 2.1 percent of 949 - 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 949 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 949 is 100%, so we can write it down as 949=100%.
4. We know, that x is 2.1% of the output value, so we can write it down as x=2.1%.
5. Now we have two simple equations:
1) 949=100%
2) x=2.1%
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:
949/x=100%/2.1%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 2.1% of 949

949/x=100/2.1
(949/x)*x=(100/2.1)*x       - we multiply both sides of the equation by x
949=47.619047619048*x       - we divide both sides of the equation by (47.619047619048) to get x
949/47.619047619048=x
19.929=x
x=19.929

now we have:
2.1% of 949=19.929
