P. 140
Type Study The top of the picture shows a log and 5 lollipops, and the bottom now shows
9 lollipops. Since the lengths of the top of the picture and the bottom of the
picture are the same, the length of the log can be found by subtracting
9-5=4 lollipops.
The length of each pair of scissors is the same as 3 lollipops, and the length of
the log is 4 lollipops. The log is 1 lollipop longer than the pair of scissors.
Problem solving
1 When the stick is divided into four equal parts, one part is the same length as 2
unit lengths.
The length of the stick is 2^4=8 unit lengths.
2 Ribbon B is 1 matchstick longer than ribbon A. The following picture shows the
length of each ribbon in matchsticks.
AA
C
D
The length of ribbon C is 6 matchsticks.
The picture given below shows what the top part of the ribbon would look like
when unfolded.
The folded part is the length of one square on the grid, which is 1 cm.
The length of the ribbon is 3+1+2+1+2+1+2+1+2=15 cm.
