Bob has 8754 Tim has 4839 the value of 8 in Bob number is how many times greater than the 8 in tim number

To compare between the numbers take the nber as a percentage or a fraction:

(8/8754) * 100=0.091%

(8/4839) * 100=0.165%

0.165 is greater than 0.091 so the value of 8 in Tim number is greater.

In an easier way the greater the donominator the lower the value of that number. Hence 8/8754 is less than 8/4839
