What is 0.7 percent of 670 - 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 670 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 670 is 100%, so we can write it down as 670=100%.
4. We know, that x is 0.7% of the output value, so we can write it down as x=0.7%.
5. Now we have two simple equations:
1) 670=100%
2) x=0.7%
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:
670/x=100%/0.7%
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 0.7% of 670

670/x=100/0.7
(670/x)*x=(100/0.7)*x       - we multiply both sides of the equation by x
670=142.85714285714*x       - we divide both sides of the equation by (142.85714285714) to get x
670/142.85714285714=x
4.69=x
x=4.69

now we have:
0.7% of 670=4.69
