Proportional numbers are numbers with the same equivalent ratio
98/126 is proportional to 84/108
The number is given as:

Reduce fraction to the lowest term

Reduce 86/110 to the lowest term

Divide by 2/2

43/55 is not equivalent to 7/9
Reduce 98/126 to the lowest term

Divide by 14/14

7/9 is equivalent to 7/9.
Hence, 98/126 is proportional to 84/108
