What is 7.7 percent of 145 - 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 145 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 145 is 100%, so we can write it down as 145=100%.
4. We know, that x is 7.7% of the output value, so we can write it down as x=7.7%.
5. Now we have two simple equations:
1) 145=100%
2) x=7.7%
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:
145/x=100%/7.7%
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 7.7% of 145

145/x=100/7.7
(145/x)*x=(100/7.7)*x       - we multiply both sides of the equation by x
145=12.987012987013*x       - we divide both sides of the equation by (12.987012987013) to get x
145/12.987012987013=x
11.165=x
x=11.165

now we have:
7.7% of 145=11.165
