The number 61.75 has what a scientist would refer to as four significant digits. If you only were able to be accurate to a single digit, then you would approximate that amount to 60, or 6 times ten to the first power.
93 and 7 would be an example.

You would need 20 twos to number the pages from 1 to 232. This is because there are 20 occurrences of the digit two in the numbers from 1 to 232.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. It would appear that that is the case for this number.
If you allow non integers, then your smallest four-digit number would be .0001. If you only allow integers, then your smallest four-digit number would be 1000. Your largest four-digit number would be 9999.
There are 9 pages that use a single digit (pages 1-9), leaving 495 digits - 9 pages × 1 digit/page = 486 digits There are 90 pages that use 2 digits (pages 10-99), leaving 486 digits - 90 pages × 2 digits/page = 306 digits There are 900 pages that use 3 digits (pages 100-999); this would be 2,700 digits, so the number of pages is somewhere in the hundreds. 306 digits ÷ 3 digits/page = 102 pages in the hundreds. → total number of pages = 102 + 90 + 9 = 201 pages.
I would just call it a "400-digit number".
