78 is what percent of 703 - 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 703 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 703, so we can write it down as 100%=703.
4. We know, that x% equals 78 of the output value, so we can write it down as x%=78.
5. Now we have two simple equations:
1) 100%=703
2) x%=78
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%=703/78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 78 is what percent of 703

100%/x%=703/78
(100/x)*x=(703/78)*x       - we multiply both sides of the equation by x
100=9.0128205128205*x       - we divide both sides of the equation by (9.0128205128205) to get x
100/9.0128205128205=x
11.095305832148=x
x=11.095305832148

now we have:
78 is 11.095305832148% of 703
