What is 30.7 percent of 253 - 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 253 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 253 is 100%, so we can write it down as 253=100%.
4. We know, that x is 30.7% of the output value, so we can write it down as x=30.7%.
5. Now we have two simple equations:
1) 253=100%
2) x=30.7%
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:
253/x=100%/30.7%
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 30.7% of 253

253/x=100/30.7
(253/x)*x=(100/30.7)*x       - we multiply both sides of the equation by x
253=3.257328990228*x       - we divide both sides of the equation by (3.257328990228) to get x
253/3.257328990228=x
77.671=x
x=77.671

now we have:
30.7% of 253=77.671
