What is 49 percent of 397 - 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 397 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 397 is 100%, so we can write it down as 397=100%.
4. We know, that x is 49% of the output value, so we can write it down as x=49%.
5. Now we have two simple equations:
1) 397=100%
2) x=49%
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:
397/x=100%/49%
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 49% of 397

397/x=100/49
(397/x)*x=(100/49)*x       - we multiply both sides of the equation by x
397=2.0408163265306*x       - we divide both sides of the equation by (2.0408163265306) to get x
397/2.0408163265306=x
194.53=x
x=194.53

now we have:
49% of 397=194.53
