What is 0.5 percent of 331 - 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 331 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 331 is 100%, so we can write it down as 331=100%.
4. We know, that x is 0.5% of the output value, so we can write it down as x=0.5%.
5. Now we have two simple equations:
1) 331=100%
2) x=0.5%
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:
331/x=100%/0.5%
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 0.5% of 331

331/x=100/0.5
(331/x)*x=(100/0.5)*x       - we multiply both sides of the equation by x
331=200*x       - we divide both sides of the equation by (200) to get x
331/200=x
1.655=x
x=1.655

now we have:
0.5% of 331=1.655
