92 is what percent of 1979 - 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 1979 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 1979, so we can write it down as 100%=1979.
4. We know, that x% equals 92 of the output value, so we can write it down as x%=92.
5. Now we have two simple equations:
1) 100%=1979
2) x%=92
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%=1979/92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 92 is what percent of 1979

100%/x%=1979/92
(100/x)*x=(1979/92)*x       - we multiply both sides of the equation by x
100=21.510869565217*x       - we divide both sides of the equation by (21.510869565217) to get x
100/21.510869565217=x
4.6488125315816=x
x=4.6488125315816

now we have:
92 is 4.6488125315816% of 1979
