Answer:
We have the numbers 98*50 and 97*50, here we can see that in both numbers we have a common factor, 50
So we can write the difference as:
98*50 - 97*50 = (98 - 97)*50 = 1*50 = 50
So the difference is equal to 50, wich means that the first one is 50 units bigger than the second.
The ratio can be calculated as:
98*50/(97*50) = (98/97)*(50/50) =98/97
Wich means that the first one is 98/97 times bigger than the second.
