Đáp án:

The denominator is 45 so it is divisible by 5 and 9 divisible by 5 numbers ending in 0 or 5 divisible by 9 sum of digits divisible by 9 is divisible by 9 consider eg b = 0 we have 1a830 divisible by 9 => 1+a+ 8+3+0 is divisible by 9 => a = 6

Hok tốt

để ps 1a83b/ 45 thì 1a83b phai chia hết cho 5 và 9. Mà để chia hết cho 5 thì b phải bằng 5 hoặc 0

Nếu b= 0 thì 1a830 chia hết cho 9 ta có: (1+ a+ 8+ 3+ 0) chia hết cho 9= (12+ a) chia hết cho 9 => a= 6

Nếu b= 5 thì 1a835 chia hết cho 9 ta có: ( 1+ a+ 8+ 3+ 5) chia hết cho 9= (17+ a) chia hết cho 9 => a= 1

Với b= 0 thì a= 6

Với b= 5 thì a= 1
