What is 90.3 percent of 6.9 - 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 6.9 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 6.9 is 100%, so we can write it down as 6.9=100%.
4. We know, that x is 90.3% of the output value, so we can write it down as x=90.3%.
5. Now we have two simple equations:
1) 6.9=100%
2) x=90.3%
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:
6.9/x=100%/90.3%
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 90.3% of 6.9

6.9/x=100/90.3
(6.9/x)*x=(100/90.3)*x       - we multiply both sides of the equation by x
6.9=1.1074197120709*x       - we divide both sides of the equation by (1.1074197120709) to get x
6.9/1.1074197120709=x
6.2307=x
x=6.2307

now we have:
90.3% of 6.9=6.2307
