Question

Replace _ by the smallest number to make it divisible by 11 , 467_91 please also give the procedure also

Answer 1

4+7+9=20
6+1=7

20-7=13

The number closest to 13 and divisible by 11 is 11. so _ can be replaced by 2.

Checking:
4+7+9=20
6+2+1=9

20-9=11

Answer 2

Answer:

_ = 2

Step-by-step explanation:

Divisibility Rule of 11 = The difference of the sum of the digit at even place and sum of the digit at odd place is must be 0 or multiple of 11.

467_91

Sum of odd place = 4 + 7 + 9 = 20

Sum of Even places = 6 + _ +1 = 7 + _

Difference

20 - ( 7 + _ ) = 13 - _

13 - _ should be equal to 0 or multiple of 11.

so smallest number that can make it 11 is 2

Therefore, the smallest number is that replaces _ is 2
