0.62 is what percent of 21.78 - 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 21.78 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 21.78, so we can write it down as 100%=21.78.
4. We know, that x% equals 0.62 of the output value, so we can write it down as x%=0.62.
5. Now we have two simple equations:
1) 100%=21.78
2) x%=0.62
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%=21.78/0.62
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.62 is what percent of 21.78

100%/x%=21.78/0.62
(100/x)*x=(21.78/0.62)*x       - we multiply both sides of the equation by x
100=35.129032258065*x       - we divide both sides of the equation by (35.129032258065) to get x
100/35.129032258065=x
2.8466483011938=x
x=2.8466483011938

now we have:
0.62 is 2.8466483011938% of 21.78
