10 is what percent of 1422 - 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 1422 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 1422, so we can write it down as 100%=1422.
4. We know, that x% equals 10 of the output value, so we can write it down as x%=10.
5. Now we have two simple equations:
1) 100%=1422
2) x%=10
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%=1422/10
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10 is what percent of 1422

100%/x%=1422/10
(100/x)*x=(1422/10)*x       - we multiply both sides of the equation by x
100=142.2*x       - we divide both sides of the equation by (142.2) to get x
100/142.2=x
0.70323488045007=x
x=0.70323488045007

now we have:
10 is 0.70323488045007% of 1422
