What is 90.78 percent of 76 - 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 76 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 76 is 100%, so we can write it down as 76=100%.
4. We know, that x is 90.78% of the output value, so we can write it down as x=90.78%.
5. Now we have two simple equations:
1) 76=100%
2) x=90.78%
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:
76/x=100%/90.78%
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 90.78% of 76

76/x=100/90.78
(76/x)*x=(100/90.78)*x       - we multiply both sides of the equation by x
76=1.1015642211941*x       - we divide both sides of the equation by (1.1015642211941) to get x
76/1.1015642211941=x
68.9928=x
x=68.9928

now we have:
90.78% of 76=68.9928
