What is 21.5 percent of 675 - 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 675 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 675 is 100%, so we can write it down as 675=100%.
4. We know, that x is 21.5% of the output value, so we can write it down as x=21.5%.
5. Now we have two simple equations:
1) 675=100%
2) x=21.5%
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:
675/x=100%/21.5%
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 21.5% of 675

675/x=100/21.5
(675/x)*x=(100/21.5)*x       - we multiply both sides of the equation by x
675=4.6511627906977*x       - we divide both sides of the equation by (4.6511627906977) to get x
675/4.6511627906977=x
145.125=x
x=145.125

now we have:
21.5% of 675=145.125
