89 is what percent of 1799 - 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 1799 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 1799, so we can write it down as 100%=1799.
4. We know, that x% equals 89 of the output value, so we can write it down as x%=89.
5. Now we have two simple equations:
1) 100%=1799
2) x%=89
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%=1799/89
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 89 is what percent of 1799

100%/x%=1799/89
(100/x)*x=(1799/89)*x       - we multiply both sides of the equation by x
100=20.213483146067*x       - we divide both sides of the equation by (20.213483146067) to get x
100/20.213483146067=x
4.9471928849361=x
x=4.9471928849361

now we have:
89 is 4.9471928849361% of 1799
