210.5 is what percent of 774 - 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 774 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 774, so we can write it down as 100%=774.
4. We know, that x% equals 210.5 of the output value, so we can write it down as x%=210.5.
5. Now we have two simple equations:
1) 100%=774
2) x%=210.5
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%=774/210.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 210.5 is what percent of 774

100%/x%=774/210.5
(100/x)*x=(774/210.5)*x       - we multiply both sides of the equation by x
100=3.6769596199525*x       - we divide both sides of the equation by (3.6769596199525) to get x
100/3.6769596199525=x
27.196382428941=x
x=27.196382428941

now we have:
210.5 is 27.196382428941% of 774
