    check that last digit is even, otherwise 6174 can't be divisible by 4. 61 7 4 (Separate the last 2 digits from the rest of the number) 4 ÷ 2 = 2 (last digit divided by 2) 7 + 2 = 9 (Add half of last digit to the penultimate digit) Since 9 isn't even, 6174 is not divisible by 4; Third method. 1720 (The original number)

  3. Irreducible fraction - Wikipedia

    en.wikipedia.org/wiki/Irreducible_fraction

    The notion of irreducible fraction generalizes to the field of fractions of any unique factorization domain: any element of such a field can be written as a fraction in which denominator and numerator are coprime, by dividing both by their greatest common divisor. [7] This applies notably to rational expressions over a field. The irreducible ...

    en.wikipedia.org/wiki/Simplification

    Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include: Simplification of algebraic expressions, in computer algebra; Simplification of boolean expressions i.e. logic optimization

  5. Fraction - Wikipedia

    en.wikipedia.org/wiki/Fraction

    Any integer can be written as a fraction with the number one as denominator. For example, 17 can be written as ⁠ 17 / 1 ⁠, where 1 is sometimes referred to as the invisible denominator. [17] Therefore, every fraction or integer, except for zero, has a reciprocal. For example, the reciprocal of 17 is ⁠ 1 / 17 ⁠.

    [2] [3] Thus, in the expression 1 + 2 × 3, the multiplication is performed before addition, and the expression has the value 1 + (2 × 3) = 7, and not (1 + 2) × 3 = 9. When exponents were introduced in the 16th and 17th centuries, they were given precedence over both addition and multiplication and placed as a superscript to the right of ...
