What is 6.75 percent of 42 - 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 42 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 42 is 100%, so we can write it down as 42=100%.
4. We know, that x is 6.75% of the output value, so we can write it down as x=6.75%.
5. Now we have two simple equations:
1) 42=100%
2) x=6.75%
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:
42/x=100%/6.75%
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 6.75% of 42

42/x=100/6.75
(42/x)*x=(100/6.75)*x       - we multiply both sides of the equation by x
42=14.814814814815*x       - we divide both sides of the equation by (14.814814814815) to get x
42/14.814814814815=x
2.835=x
x=2.835

now we have:
6.75% of 42=2.835
