21 is what percent of 1461 - 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 1461 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 1461, so we can write it down as 100%=1461.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=1461
2) x%=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:
100%/x%=1461/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21 is what percent of 1461

100%/x%=1461/21
(100/x)*x=(1461/21)*x       - we multiply both sides of the equation by x
100=69.571428571429*x       - we divide both sides of the equation by (69.571428571429) to get x
100/69.571428571429=x
1.4373716632444=x
x=1.4373716632444

now we have:
21 is 1.4373716632444% of 1461
