What is 0.103 percent of 620 - 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 620 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 620 is 100%, so we can write it down as 620=100%.
4. We know, that x is 0.103% of the output value, so we can write it down as x=0.103%.
5. Now we have two simple equations:
1) 620=100%
2) x=0.103%
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:
620/x=100%/0.103%
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 0.103% of 620

620/x=100/0.103
(620/x)*x=(100/0.103)*x       - we multiply both sides of the equation by x
620=970.87378640777*x       - we divide both sides of the equation by (970.87378640777) to get x
620/970.87378640777=x
0.6386=x
x=0.6386

now we have:
0.103% of 620=0.6386
