PAGE 54 QJ Find the cost of these: Here are 10 rows of 5 stickers. QJ Use your straw to split
a 7 stamps at 6p each b 9 stamps at 5p each the block of stickers into
6 rows and 4 rows.
c 8 stamps at 4p each d 7 stamps at 3p each
e 5 stamps at 3p and 8 stamps at 6p each
f 8 stamps at 10p and 6 stamps at 2p each.
I]] Try to find the cost of these without a calculator.
Write down what you do.
a 5 pencils at 14p each b 6 mini-bars at 11 peach
c 7 apples at 12p each d 5 comics at 18p each
e 4 dice at 16p each f 12 marbles at 8p each )
....

[II Now split the stickers
in each of these ways.
Write about each one.
I]] Use your calculator to find the cost of these.
Write your answers as pounds and pence, for example £0·88. a 5 rows and 5 rows
b 3 rows and 7 rows
a 4 of these b 6 of these 5 x 10 = 50 c 8 rows and 2 rows
d 1 row and 9 rows
