98 is what percent of 142.9 - 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 142.9 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 142.9, so we can write it down as 100%=142.9.
4. We know, that x% equals 98 of the output value, so we can write it down as x%=98.
5. Now we have two simple equations:
1) 100%=142.9
2) x%=98
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%=142.9/98
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 98 is what percent of 142.9

100%/x%=142.9/98
(100/x)*x=(142.9/98)*x       - we multiply both sides of the equation by x
100=1.4581632653061*x       - we divide both sides of the equation by (1.4581632653061) to get x
100/1.4581632653061=x
68.579426172148=x
x=68.579426172148

now we have:
98 is 68.579426172148% of 142.9
