What is 68 mod 9?

Often represented by the operator "mod", the modulo is a mathematical operation that gives the remainder of an integer division.

The result of 68 mod 9 is 5.

How to compute 68 mod 9?

The simplest approach is to use the "mod" operator (often denoted as "%" in many programming languages), but you could do it manually in the following way:

Remainder = N − ( M × ⌊ N M ⌋ )

(where N is the dividend, M is the divisor and ⌊ N M ⌋ represents the integer part of the quotient)

  1. 68 / 9 = 7.5555555555556
  2. ⌊7.5555555555556⌋ = 7 (We only keep the integer part)
  3. 9 × 7 = 63
  4. 68 - 63 = 5 (Subtracting gives us the remainder)

In short: 68 − (9 × ⌊68 / 9⌋) = 5

Is 68 divisible by 9?

A number is said to be divisible by another number, if the remainder of the division is zero.

Given that the result of 68 mod 9 is 5, this indicates that dividing 68 by 9 leaves a remainder of 5. Therefore, no, since the remainder isn't zero, 68 is not divisible by 9.
