1.87 is what percent of 0.21 - 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 0.21 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 0.21, so we can write it down as 100%=0.21.
4. We know, that x% equals 1.87 of the output value, so we can write it down as x%=1.87.
5. Now we have two simple equations:
1) 100%=0.21
2) x%=1.87
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%=0.21/1.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.87 is what percent of 0.21

100%/x%=0.21/1.87
(100/x)*x=(0.21/1.87)*x       - we multiply both sides of the equation by x
100=0.11229946524064*x       - we divide both sides of the equation by (0.11229946524064) to get x
100/0.11229946524064=x
890.47619047619=x
x=890.47619047619

now we have:
1.87 is 890.47619047619% of 0.21
