77 is what percent of 1782 - 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 1782 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 1782, so we can write it down as 100%=1782.
4. We know, that x% equals 77 of the output value, so we can write it down as x%=77.
5. Now we have two simple equations:
1) 100%=1782
2) x%=77
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%=1782/77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77 is what percent of 1782

100%/x%=1782/77
(100/x)*x=(1782/77)*x       - we multiply both sides of the equation by x
100=23.142857142857*x       - we divide both sides of the equation by (23.142857142857) to get x
100/23.142857142857=x
4.320987654321=x
x=4.320987654321

now we have:
77 is 4.320987654321% of 1782
