Suppose b is an integer. If b mod 12 = 5, what is 8b mod 12? In other words, if division of b by 12 gives a remainder of 5, what is the remainder when 8b is divided by 12

8 b mod 12 is equal to 4.

Step-by-step explanation:

Use Dividend = Divisor × Quotient + Remainder

As b mod 12 = 5 (that is division of b by 12 gives a remainder of 5)

Here, k is any integer.

Multiply both sides of by 8

write 40 in terms of 12

Therefore,

8 b mod 12 is equal to 4.

21
