What is 47 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 47 mod 9 is 2.

How to compute 47 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. 47 / 9 = 5.2222222222222
  2. ⌊5.2222222222222⌋ = 5 (We only keep the integer part)
  3. 9 × 5 = 45
  4. 47 - 45 = 2 (Subtracting gives us the remainder)

In short: 47 − (9 × ⌊47 / 9⌋) = 2

Is 47 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 47 mod 9 is 2, this indicates that dividing 47 by 9 leaves a remainder of 2. Therefore, no, since the remainder isn't zero, 47 is not divisible by 9.
