What is 41.5 percent of 321 - 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 321 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 321 is 100%, so we can write it down as 321=100%.
4. We know, that x is 41.5% of the output value, so we can write it down as x=41.5%.
5. Now we have two simple equations:
1) 321=100%
2) x=41.5%
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:
321/x=100%/41.5%
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 41.5% of 321

321/x=100/41.5
(321/x)*x=(100/41.5)*x       - we multiply both sides of the equation by x
321=2.4096385542169*x       - we divide both sides of the equation by (2.4096385542169) to get x
321/2.4096385542169=x
133.215=x
x=133.215

now we have:
41.5% of 321=133.215
