Question

Replace the * with the smallest digit to make it divisible by 11 71*8965

Answer 1

Answer:

8

Step-by-step explanation:

5+9+*+7 =21+*

6+8+1 = 15

21 + 15 = 36

36 is not divisible by 11

but after this 44 is divisible by 11

so 36+8 = 44

Answer 2

Answer:

The correct the answer is

5

CONCEPT

A divisibility test is a simple thanks to identify whether the given number is split by a hard and fast divisor without actually performing the division process. If variety is totally divided by another number, then the quotient should be a full number and therefore the remainder should be zero. A divisibility rule may be a reasonably shortcut that helps us to spot if a given integer is divisible by a divisor by examining its digits, without performing the entire division process. Multiple divisibility rules will be applied to the identical number which may quickly determine its prime factorization.

Given

Number = 11 71*8965

To find:

Replace the * with the smallest digit to make it divisible by 11 71*8965

Step-by-step explanation:

It is divisible by 11 is

7+*+9+5 = 21+*

1+8+6 = 15

21 + * - 15 = divisible by 11

So,

  21-15= 6

   6 + * = 11

*= 11-6

*= 5
