What is 1.55 percent of 30.68 - 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 30.68 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 30.68 is 100%, so we can write it down as 30.68=100%.
4. We know, that x is 1.55% of the output value, so we can write it down as x=1.55%.
5. Now we have two simple equations:
1) 30.68=100%
2) x=1.55%
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:
30.68/x=100%/1.55%
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 1.55% of 30.68

30.68/x=100/1.55
(30.68/x)*x=(100/1.55)*x       - we multiply both sides of the equation by x
30.68=64.516129032258*x       - we divide both sides of the equation by (64.516129032258) to get x
30.68/64.516129032258=x
0.47554=x
x=0.47554

now we have:
1.55% of 30.68=0.47554
