0.03 is what percent of 1521 - 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 1521 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 1521, so we can write it down as 100%=1521.
4. We know, that x% equals 0.03 of the output value, so we can write it down as x%=0.03.
5. Now we have two simple equations:
1) 100%=1521
2) x%=0.03
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%=1521/0.03
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.03 is what percent of 1521

100%/x%=1521/0.03
(100/x)*x=(1521/0.03)*x       - we multiply both sides of the equation by x
100=50700*x       - we divide both sides of the equation by (50700) to get x
100/50700=x
0.0019723865877712=x
x=0.0019723865877712

now we have:
0.03 is 0.0019723865877712% of 1521
