What is 45.5 percent of 1378 - 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 1378 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 1378 is 100%, so we can write it down as 1378=100%.
4. We know, that x is 45.5% of the output value, so we can write it down as x=45.5%.
5. Now we have two simple equations:
1) 1378=100%
2) x=45.5%
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:
1378/x=100%/45.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 45.5% of 1378

1378/x=100/45.5
(1378/x)*x=(100/45.5)*x       - we multiply both sides of the equation by x
1378=2.1978021978022*x       - we divide both sides of the equation by (2.1978021978022) to get x
1378/2.1978021978022=x
626.99=x
x=626.99

now we have:
45.5% of 1378=626.99
