Cody needed exactly 70 m of cloth to make 16 short identical flags and 8 long identical flags. He had some cloth which was just enough to make all the short flags and 4 long flags. He used 139¹₂ cm for each short flag.

1. How much cloth would he need to make 1 long flag?
2. How much cloth was he short of to make the remaining long flags?

(a)
Length of 16 short flags + Length of 8 long flags = 70 m

1 m = 100 cm

Length of cloth for each short flag
= 139¹₂ cm
= 139.5 cm 
= 1.395 m

Length of cloth for 16 short flags
= 16 x 1.395 
= 22.32 m

Length of cloth for 8 long flags
= 70 - 22.32
= 47.68 m

Length of cloth to make 1 long flag
= 47.68 ÷ 8
= 5.96 m

(b)
Number of remaining long flags that Cody needed
= 8 - 4
= 4

Length of cloth that he was short of
= Length of 4 long flags
= 4 x 5.96
= 23.84 m

Answer(s): (a) 5.96 m; (b) 23.84 m
