the second pack

Explanation:

In order to determine which pack of chicken ways more, we must first make sure that the given masses of the two packs are in the same units.

Knowing that #1color(white)(i)"pound"=16color(white)(i)"ounces"#, we can convert #3color(white)(i)"pounds"# into ounces.

#3color(white)(i)"pounds"xx(16color(white)(i)"ounces")/("pound")#

#=3color(white)(i)color(red)cancelcolor(black)("pounds")xx(16color(white)(i)"ounces")/color(red)cancelcolor(black)("pound")#

#=3xx16color(white)(i)"ounces"#

#=48color(white)(i)"ounces"#

Now that the masses of the two packs are both in ounces, we can clearly see that:

#48color(white)(i)"ounces">45color(white)(i)"ounces"#

Hence, the second pack of chicken ways more.
