Each person would get \frac{5}{8} pizza.

Solution:

Total quantity of pizza = 1\frac{7}{8}

Number of persons shared = 3

To find how much pizza would each person get:

Let us first convert  improper fraction into mixed fraction.

$1\frac{7}{8}=\frac{1\times8 + 7}{8}=\frac{15}{8}

Now divide the total quantity of pizza by the number persons shared.

$\text{Quantity of pizza each person get}=\frac{(\frac{15}{8}) }{3}

                                                    $=\frac{15}{8\times3}

                                                    $=\frac{15}{24}

Divide both numerator and denominator by 3.

                                                    $=\frac{15\div3}{24\div3}

                                                    $=\frac{5}{8}

Quantity of pizza each person get = \frac{5}{8}

Hence each person would get \frac{5}{8} pizza.
