1.62 is what percent of 90000000 - 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 90000000 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 90000000, so we can write it down as 100%=90000000.
4. We know, that x% equals 1.62 of the output value, so we can write it down as x%=1.62.
5. Now we have two simple equations:
1) 100%=90000000
2) x%=1.62
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%=90000000/1.62
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.62 is what percent of 90000000

100%/x%=90000000/1.62
(100/x)*x=(90000000/1.62)*x       - we multiply both sides of the equation by x
100=55555555.555556*x       - we divide both sides of the equation by (55555555.555556) to get x
100/55555555.555556=x
1.8E-6=x
x=1.8E-6

now we have:
1.62 is 1.8E-6% of 90000000
