What is 105 percent of 672 - 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 672 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 672 is 100%, so we can write it down as 672=100%.
4. We know, that x is 105% of the output value, so we can write it down as x=105%.
5. Now we have two simple equations:
1) 672=100%
2) x=105%
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:
672/x=100%/105%
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 105% of 672

672/x=100/105
(672/x)*x=(100/105)*x       - we multiply both sides of the equation by x
672=0.95238095238095*x       - we divide both sides of the equation by (0.95238095238095) to get x
672/0.95238095238095=x
705.6=x
x=705.6

now we have:
105% of 672=705.6
