What is 175 percent of 4.2 - 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 4.2 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 4.2 is 100%, so we can write it down as 4.2=100%.
4. We know, that x is 175% of the output value, so we can write it down as x=175%.
5. Now we have two simple equations:
1) 4.2=100%
2) x=175%
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:
4.2/x=100%/175%
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 175% of 4.2

4.2/x=100/175
(4.2/x)*x=(100/175)*x       - we multiply both sides of the equation by x
4.2=0.57142857142857*x       - we divide both sides of the equation by (0.57142857142857) to get x
4.2/0.57142857142857=x
7.35=x
x=7.35

now we have:
175% of 4.2=7.35
