What is 7.4 percent of 140 - 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 140 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 140 is 100%, so we can write it down as 140=100%.
4. We know, that x is 7.4% of the output value, so we can write it down as x=7.4%.
5. Now we have two simple equations:
1) 140=100%
2) x=7.4%
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:
140/x=100%/7.4%
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 7.4% of 140

140/x=100/7.4
(140/x)*x=(100/7.4)*x       - we multiply both sides of the equation by x
140=13.513513513514*x       - we divide both sides of the equation by (13.513513513514) to get x
140/13.513513513514=x
10.36=x
x=10.36

now we have:
7.4% of 140=10.36
