91 since the ones digit is 8 less than 9 and the two digits, 9+1 = 10, a two-digit number.
It is 58.
111111 Any 6 digit number less than that would require a 0, which is an even number.
56. Tens digit is greater than 4 and less than 6 so it can only be 5, so the number is 5X. It is one less than the number whose digits sum to 12, so its digits sum to 12-1 = 11 → 5 + X = 11 → X = 11 - 5 = 6 → the number is 56.
The answer is -5300.
It is 0.88887

A) If a number has two digits, then the sum of its digits is less than the value of the original two-digit number.
No, a 4-digit number is not always less than a 5-digit number. The value of a number is determined by the digits it contains, not the number of digits. For example, the 4-digit number 9999 is greater than the 5-digit number 1000. It is important to consider the actual numerical value when comparing numbers, not just the number of digits.
Answer 18. The two digit numbers less than 50 whose digits add to 9 are 45, 36, 27 and 18. 36 and 18 are even. 36 is the only number whose paired factor with 2 is even (18).
To total 17 the two digits must be 8 and 9! The original number was 98.
