Identify the most
reasonable units to measure the weight
of the choices below. So we have an average
adult, a slice of bread, a kitchen table,
or a pack of gum. So I am an average
adult, and I know that I weigh about 160 pounds. So I know that pounds are
a pretty good measurement for about something
the weight of an adult. So I'll put adults in that
category right over there. Now we have a single
slice of bread. So even a full loaf of
bread doesn't weigh a lot. Maybe that gets close to a
pound, but a slice of bread is going to be
less than a pound. So I would do this in ounces. A kitchen table. Well, a kitchen table
kind of weighs the same-- it could, if it's a very
large kitchen table, could weigh the same
or more than an adult. So I would do this in pounds. And then a pack of gum. So once again, a pack
of gum is fairly light. If you've ever been
to the gym and held even a 1-pound or
2-pound weight, it weighs more
than a pack of gum. So a pack of gum is going
to be less than a pound, so ounces seem to
make sense here.
