What is 1.55 percent of 550 - 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 550 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 550 is 100%, so we can write it down as 550=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) 550=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:
550/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 550

550/x=100/1.55
(550/x)*x=(100/1.55)*x       - we multiply both sides of the equation by x
550=64.516129032258*x       - we divide both sides of the equation by (64.516129032258) to get x
550/64.516129032258=x
8.525=x
x=8.525

now we have:
1.55% of 550=8.525
