Product is the result of multiplying the numbers, so the product of 8/15, 6/5,1/3 means that we have to multiply the three numbers, like this:
[tex] \frac{8}{15} * \frac{6}{5} * \frac{1}{3} [/tex]
let's make them into one fraction:
[tex] \frac{8*6*1}{15*5*3} [/tex]
We can simplyfy:
[tex] \frac{8*6}{15*5*3} [/tex]
[tex] \frac{8*2}{15*5} [/tex]
and multiply:
[tex] \frac{16}{75} [/tex]
and this is the correct answer!
