Lin has 27 marbles. He divides them into 3 equal groups and gives 1 group to Jill. Jill then gives 2 of hers away. How many marbles does Jill have now?
Let
m
=
marbles Jill has now. Show all your work in the space provided below. Write this in the box below.
Lin divides 27 marbles into 3 equal groups, so each group has 27/3 = 9 marbles.
Lin gives one of these groups to Jill, so Jill now has 9 marbles.
Jill gives 2 of her marbles away, so she now has 9-2 = 7 marbles.
Therefore, Jill has 7 marbles now.
m = 7
