Problem solving
1 Lisa has a 1-g and a 2-g weight, and Tom has a 2-g Key Points
and a 4-g weight. When they combine their weights
and use only one side of a balance, what masses When Lisa and Tom
can be measured? combine all their
weights, there are
one 1-g, two 2-g,
and one 4-g weights.
Therefore, the
heaviest mass that
can be measured is
1 2 2 4 9 g.
2 One 1-g weight, one 2-g weight, and one 5-g The lightest mass that
weight can be placed on one side of a balance to can be measured is 1
find different masses. Find the masses that can be g and the heaviest
measured using these weights and a balance. mass that can be
measured is
1 2 5 8 g.
