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.
