87 is what percent of 3740 - 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 3740 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 3740, so we can write it down as 100%=3740.
4. We know, that x% equals 87 of the output value, so we can write it down as x%=87.
5. Now we have two simple equations:
1) 100%=3740
2) x%=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%=3740/87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 87 is what percent of 3740

100%/x%=3740/87
(100/x)*x=(3740/87)*x       - we multiply both sides of the equation by x
100=42.988505747126*x       - we divide both sides of the equation by (42.988505747126) to get x
100/42.988505747126=x
2.3262032085561=x
x=2.3262032085561

now we have:
87 is 2.3262032085561% of 3740
