20 is what percent of 74000000 - 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 74000000 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 74000000, so we can write it down as 100%=74000000.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=74000000
2) x%=20
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%=74000000/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 74000000

100%/x%=74000000/20
(100/x)*x=(74000000/20)*x       - we multiply both sides of the equation by x
100=3700000*x       - we divide both sides of the equation by (3700000) to get x
100/3700000=x
2.7027027027027E-5=x
x=2.7027027027027E-5

now we have:
20 is 2.7027027027027E-5% of 74000000
