What is 310 percent of 15.8 - 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 15.8 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 15.8 is 100%, so we can write it down as 15.8=100%.
4. We know, that x is 310% of the output value, so we can write it down as x=310%.
5. Now we have two simple equations:
1) 15.8=100%
2) x=310%
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:
15.8/x=100%/310%
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 310% of 15.8

15.8/x=100/310
(15.8/x)*x=(100/310)*x       - we multiply both sides of the equation by x
15.8=0.32258064516129*x       - we divide both sides of the equation by (0.32258064516129) to get x
15.8/0.32258064516129=x
48.98=x
x=48.98

now we have:
310% of 15.8=48.98
