There are 10 numbers (7, 17, 27, 37, 47, 57, 67, 77, 87, 97) with 7 in the units place, 10 numbers (70, 71, 72, 73, 74, 75, 76, 77, 78, 79) with 7 in the tens place, and the number 7 itself.
Therefore, the digit 7 appears 19 times from 1 to 100.

Between 1-100- 11 zero's- ie., 10,20,30,40,.... 100... so 11*10=110
100/1 = 100 Therefore, 100 is 100 times larger than 1.
