There is decreased by $1\dfrac{5}{8}$ points in stock after three days and negative integer is used to represent.

Step-by-step explanation:

Since we have given that

Point decreased by on Monday = $\dfrac{1}{2}$

Point decreased by on Tuesday = $\dfrac{3}{4}$

Point decreased by on Wednesday = $\dfrac{3}{8}$

So, total decreased in these three days are

$\dfrac{1}{2}+\dfrac{3}{4}+\dfrac{3}{8}\\\\=\dfrac{4+6+3}{8}\\\\=\dfrac{13}{8}\\\\=1\dfrac{5}{8}$

hence, there is decreased by $1\dfrac{5}{8}$ points in stock after three days and negative integer is used to represent.
