749.83 is what percent of 840 - 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 840 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 100% equals 840, so we can write it down as 100%=840.
4. We know, that x% equals 749.83 of the output value, so we can write it down as x%=749.83.
5. Now we have two simple equations:
1) 100%=840
2) x%=749.83
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:
100%/x%=840/749.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 749.83 is what percent of 840

100%/x%=840/749.83
(100/x)*x=(840/749.83)*x       - we multiply both sides of the equation by x
100=1.1202539242228*x       - we divide both sides of the equation by (1.1202539242228) to get x
100/1.1202539242228=x
89.265476190476=x
x=89.265476190476

now we have:
749.83 is 89.265476190476% of 840
