  2. Fraction - Wikipedia

    en.wikipedia.org/wiki/Fraction

    Conversely, an improper fraction can be converted to a mixed number using division with remainder, with the proper fraction consisting of the remainder divided by the divisor. For example, since 4 goes into 11 twice, with 3 left over, 11 4 = 2 + 3 4 . {\displaystyle {\tfrac {11}{4}}=2+{\tfrac {3}{4}}.}

  3. 54 (number) - Wikipedia

    en.wikipedia.org/wiki/54_(number)

    Like all multiples of 6, [3] 54 is equal to some of its proper divisors summed together, [a] so it is also a semiperfect number. [4] These proper divisors can be summed in various ways to express all positive integers smaller than 54, so 54 is a practical number as well. [5]

  4. Proper transfer function - Wikipedia

    en.wikipedia.org/wiki/Proper_transfer_function

    A strictly proper transfer function is a transfer function where the degree of the numerator is less than the degree of the denominator. The difference between the degree of the denominator (number of poles) and degree of the numerator (number of zeros) is the relative degree of the transfer function.

  5. Rothenberg propriety - Wikipedia

    en.wikipedia.org/wiki/Rothenberg_propriety

    The twelve equal scale is strictly proper as is any equal tempered scale because it has only one interval size for each number of steps Most tempered scales are proper too. As another example, the otonal harmonic fragment 54 , 6 ⁄ 4 , 7 ⁄ 4 , 8 ⁄ 4 is strictly proper, with the one step intervals varying in size from 8 ⁄ 7 to 5 ...

    This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 32. Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters. 89

    In the second step, they were divided by 3. The final result, ⁠ 4 / 3 ⁠, is an irreducible fraction because 4 and 3 have no common factors other than 1. The original fraction could have also been reduced in a single step by using the greatest common divisor of 90 and 120, which is 30. As 120 ÷ 30 = 4, and 90 ÷ 30 = 3, one gets
