0.57 is what percent of 1.89 - 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 1.89 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 1.89, so we can write it down as 100%=1.89.
4. We know, that x% equals 0.57 of the output value, so we can write it down as x%=0.57.
5. Now we have two simple equations:
1) 100%=1.89
2) x%=0.57
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%=1.89/0.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.57 is what percent of 1.89

100%/x%=1.89/0.57
(100/x)*x=(1.89/0.57)*x       - we multiply both sides of the equation by x
100=3.3157894736842*x       - we divide both sides of the equation by (3.3157894736842) to get x
100/3.3157894736842=x
30.15873015873=x
x=30.15873015873

now we have:
0.57 is 30.15873015873% of 1.89
