What is 1.21 percent of 1.3 - 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 1.3 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 1.3 is 100%, so we can write it down as 1.3=100%.
4. We know, that x is 1.21% of the output value, so we can write it down as x=1.21%.
5. Now we have two simple equations:
1) 1.3=100%
2) x=1.21%
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:
1.3/x=100%/1.21%
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 1.21% of 1.3

1.3/x=100/1.21
(1.3/x)*x=(100/1.21)*x       - we multiply both sides of the equation by x
1.3=82.644628099174*x       - we divide both sides of the equation by (82.644628099174) to get x
1.3/82.644628099174=x
0.01573=x
x=0.01573

now we have:
1.21% of 1.3=0.01573
