21.7 is what percent of 1276 - 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 1276 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 1276, so we can write it down as 100%=1276.
4. We know, that x% equals 21.7 of the output value, so we can write it down as x%=21.7.
5. Now we have two simple equations:
1) 100%=1276
2) x%=21.7
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%=1276/21.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.7 is what percent of 1276

100%/x%=1276/21.7
(100/x)*x=(1276/21.7)*x       - we multiply both sides of the equation by x
100=58.801843317972*x       - we divide both sides of the equation by (58.801843317972) to get x
100/58.801843317972=x
1.7006269592476=x
x=1.7006269592476

now we have:
21.7 is 1.7006269592476% of 1276
