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.
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).
Possibility of two digit no whose sum is 17 89 and 98 Reverse of 89 is 98. 98 is 9 less than the original no 89. 89 is original no
