    Answer:

    I’ll setup up the problem and you can do the calculation

    Step-by-step explanation:

    Total length of string – L = 8m

    Multiple pieces is – 0.75m

    Number of multiple pieces that are 0.75m – n

    Remaining (last) piece – R

    what we need to solve

    R = L – (0.75n)

    first find n by dividing L by 0.75 taking only the whole number (throw away the fraction)

    n = 8/0.75 (I’ll leave that calculate to you)

    Then substitute n in the equation above to get R
