The average of 96, 97, 98, and 20 is 77.75 not in the 90's. You add all the numbers and divide by 4.
Designate the unknown number as n. From the problem statement, n/2 + 98 = 100, or n = 4.
From 49/98 divide both by 7 = 7/14 divide by 7 again = 1/2
If you want 98 and 70 as factors, 98x70 gives 6860.
