1.86 is what percent of 620 - 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 620 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 620, so we can write it down as 100%=620.
4. We know, that x% equals 1.86 of the output value, so we can write it down as x%=1.86.
5. Now we have two simple equations:
1) 100%=620
2) x%=1.86
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%=620/1.86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.86 is what percent of 620

100%/x%=620/1.86
(100/x)*x=(620/1.86)*x       - we multiply both sides of the equation by x
100=333.33333333333*x       - we divide both sides of the equation by (333.33333333333) to get x
100/333.33333333333=x
0.3=x
x=0.3

now we have:
1.86 is 0.3% of 620
