35 is what percent of 7.2 - 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 7.2 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 7.2, so we can write it down as 100%=7.2.
4. We know, that x% equals 35 of the output value, so we can write it down as x%=35.
5. Now we have two simple equations:
1) 100%=7.2
2) x%=35
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%=7.2/35
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 35 is what percent of 7.2

100%/x%=7.2/35
(100/x)*x=(7.2/35)*x       - we multiply both sides of the equation by x
100=0.20571428571429*x       - we divide both sides of the equation by (0.20571428571429) to get x
100/0.20571428571429=x
486.11111111111=x
x=486.11111111111

now we have:
35 is 486.11111111111% of 7.2
