Zane needed exactly 88 m of cloth to make 17 small identical flags and 9 big identical flags. He had some cloth which was just enough to make all the small flags and 5 big flags. He used 114
12 cm for each small flag.
- How much cloth would he need to make 1 big flag?
- How much cloth was he short of to make the remaining big flags?
(a)
Length of 17 small flags + Length of 9 big flags = 88 m
1 m = 100 cm
Length of cloth for each small flag
= 114
12 cm
= 114.5 cm
= 1.145 m
Length of cloth for 17 small flags
= 17 x 1.145
= 19.465 m
Length of cloth for 9 big flags
= 88 - 19.465
= 68.535 m
Length of cloth to make 1 big flag
= 68.535 ÷ 9
= 7.615 m
(b)
Number of remaining big flags that Zane needed
= 9 - 5
= 4
Length of cloth that he was short of
= Length of 4 big flags
= 4 x 7.615
= 30.46 m
Answer(s): (a) 7.615 m; (b) 30.46 m
