    The single decimal multiplier is 0.836

    Step-by-step explanation:

    In this question, we are concerned with using a single decimal multiplier to denote a 12% decrease followed by a 5% decrease.

    Let the number we want to decrease be x

    A 12% (12/100 = 0.12) decrease means x - 0.12x = 0.88x

    Now, we want to follow this up by a 5% decrease (5% = 5/100 = 0.05)

    5% decrese of 0.88x is 0.88x - 0.05 (0.88x)

    = 0.88x - 0.044x = 0.836x

    Thus, the single decimal multiplier that reflects a 12% decrease followed by a 5% decrease is 0.836
