What is 6.4 percent of 98 - 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 98 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 98 is 100%, so we can write it down as 98=100%.
4. We know, that x is 6.4% of the output value, so we can write it down as x=6.4%.
5. Now we have two simple equations:
1) 98=100%
2) x=6.4%
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:
98/x=100%/6.4%
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 6.4% of 98

98/x=100/6.4
(98/x)*x=(100/6.4)*x       - we multiply both sides of the equation by x
98=15.625*x       - we divide both sides of the equation by (15.625) to get x
98/15.625=x
6.272=x
x=6.272

now we have:
6.4% of 98=6.272
