There are 15 pies (let $x$ $x$ be 15)

Let y be the number of pieces they can sell in total

Each pie can be sold in 4 pieces: $15 \times 4$ $15xx4$

Therefore, $x \times 4 = y$ $x xx4=y$

$15 \times 4 = y$ $15xx4=y$

$y = 60$ $y=60$

See a solution process below:

Explanation:

Let's call the number of pieces we are looking for: $p$ $p$

We can then write and solve this equation using ratios:

$\frac{4 pieces}{1 pie} = \frac{p}{15 pie}$ $(4"pieces")/(1"pie") = p/(15"pie")$

$pie \cdot \frac{4 pieces}{1 pie} = pie \cdot \frac{p}{15 pie}$ $color(red)("pie") * (4"pieces")/(1"pie") = color(red)("pie") * p/(15"pie")$

$cancel(color(red)("pie")) * (4"pieces")/(1color(red)(cancel(color(black)("pie")))) = cancel(color(red)("pie")) * p/(15color(red)(cancel(color(black)("pie"))))$

$(4"pieces")/1 = p/15$

$(4"pieces") = p/15$

$color(red)(15) * (4"pieces") = color(red)(15) * p/15$

$60"pieces" = cancel(color(red)(15)) * p/color(red)(cancel(color(black)(15)))$

$60"pieces" = p$

15 pies would produce 60 pieces to sell.
