65 is what percent of 1210 - 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 1210 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 1210, so we can write it down as 100%=1210.
4. We know, that x% equals 65 of the output value, so we can write it down as x%=65.
5. Now we have two simple equations:
1) 100%=1210
2) x%=65
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%=1210/65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 65 is what percent of 1210

100%/x%=1210/65
(100/x)*x=(1210/65)*x       - we multiply both sides of the equation by x
100=18.615384615385*x       - we divide both sides of the equation by (18.615384615385) to get x
100/18.615384615385=x
5.3719008264463=x
x=5.3719008264463

now we have:
65 is 5.3719008264463% of 1210
