What is 1990 percent of 1000000 - 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 1000000 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 1000000 is 100%, so we can write it down as 1000000=100%.
4. We know, that x is 1990% of the output value, so we can write it down as x=1990%.
5. Now we have two simple equations:
1) 1000000=100%
2) x=1990%
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:
1000000/x=100%/1990%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 1990% of 1000000

1000000/x=100/1990
(1000000/x)*x=(100/1990)*x       - we multiply both sides of the equation by x
1000000=0.050251256281407*x       - we divide both sides of the equation by (0.050251256281407) to get x
1000000/0.050251256281407=x
19900000=x
x=19900000

now we have:
1990% of 1000000=19900000
