What is 42 percent of 6.875 - 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 6.875 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 6.875 is 100%, so we can write it down as 6.875=100%.
4. We know, that x is 42% of the output value, so we can write it down as x=42%.
5. Now we have two simple equations:
1) 6.875=100%
2) x=42%
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:
6.875/x=100%/42%
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 42% of 6.875

6.875/x=100/42
(6.875/x)*x=(100/42)*x       - we multiply both sides of the equation by x
6.875=2.3809523809524*x       - we divide both sides of the equation by (2.3809523809524) to get x
6.875/2.3809523809524=x
2.8875=x
x=2.8875

now we have:
42% of 6.875=2.8875
