148.3 is what percent of 215 - 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 215 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 215, so we can write it down as 100%=215.
4. We know, that x% equals 148.3 of the output value, so we can write it down as x%=148.3.
5. Now we have two simple equations:
1) 100%=215
2) x%=148.3
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%=215/148.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 148.3 is what percent of 215

100%/x%=215/148.3
(100/x)*x=(215/148.3)*x       - we multiply both sides of the equation by x
100=1.4497639919083*x       - we divide both sides of the equation by (1.4497639919083) to get x
100/1.4497639919083=x
68.976744186047=x
x=68.976744186047

now we have:
148.3 is 68.976744186047% of 215
