0.31 is what percent of 1.61 - 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 1.61 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 1.61, so we can write it down as 100%=1.61.
4. We know, that x% equals 0.31 of the output value, so we can write it down as x%=0.31.
5. Now we have two simple equations:
1) 100%=1.61
2) x%=0.31
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%=1.61/0.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.31 is what percent of 1.61

100%/x%=1.61/0.31
(100/x)*x=(1.61/0.31)*x       - we multiply both sides of the equation by x
100=5.1935483870968*x       - we divide both sides of the equation by (5.1935483870968) to get x
100/5.1935483870968=x
19.254658385093=x
x=19.254658385093

now we have:
0.31 is 19.254658385093% of 1.61
