70 is what percent of 791 - 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 791 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 791, so we can write it down as 100%=791.
4. We know, that x% equals 70 of the output value, so we can write it down as x%=70.
5. Now we have two simple equations:
1) 100%=791
2) x%=70
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%=791/70
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70 is what percent of 791

100%/x%=791/70
(100/x)*x=(791/70)*x       - we multiply both sides of the equation by x
100=11.3*x       - we divide both sides of the equation by (11.3) to get x
100/11.3=x
8.8495575221239=x
x=8.8495575221239

now we have:
70 is 8.8495575221239% of 791
