    The single decimal multiplier is 0.9152

    Step-by-step explanation:

    Here, we want to write a single decimal number that would work as to decrease an original value by 12% and increase it also by 4%

    Let the original value be x

    12% = 12/100 = 0.12

    So decreasing by 12% would be x-0.12x = 0.88x

    Now this 0.88x, we shall increase it by 4%

    4% is same as 0.04

    Thus by increasing, we have;

    0.88x + 0.04 (0.88x)

    = 0.88x + 0.0352x = 0.9152x

    So the single factor we are multiplying by is 0.9152
