70 is what percent of 1098 - 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 1098 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 1098, so we can write it down as 100%=1098.
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%=1098
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%=1098/70
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 1098

100%/x%=1098/70
(100/x)*x=(1098/70)*x       - we multiply both sides of the equation by x
100=15.685714285714*x       - we divide both sides of the equation by (15.685714285714) to get x
100/15.685714285714=x
6.3752276867031=x
x=6.3752276867031

now we have:
70 is 6.3752276867031% of 1098
