What is 2.6 percent of 172 - 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 172 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 172 is 100%, so we can write it down as 172=100%.
4. We know, that x is 2.6% of the output value, so we can write it down as x=2.6%.
5. Now we have two simple equations:
1) 172=100%
2) x=2.6%
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:
172/x=100%/2.6%
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 2.6% of 172

172/x=100/2.6
(172/x)*x=(100/2.6)*x       - we multiply both sides of the equation by x
172=38.461538461538*x       - we divide both sides of the equation by (38.461538461538) to get x
172/38.461538461538=x
4.472=x
x=4.472

now we have:
2.6% of 172=4.472
