Luis needed exactly 85 m of cloth to make 16 small identical flags and 8 big identical flags. He had some cloth which was just enough to make all the small flags and 5 big flags. He used 113
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 16 small flags + Length of 8 big flags = 85 m
1 m = 100 cm
Length of cloth for each small flag
= 113
12 cm
= 113.5 cm
= 1.135 m
Length of cloth for 16 small flags
= 16 x 1.135
= 18.16 m
Length of cloth for 8 big flags
= 85 - 18.16
= 66.84 m
Length of cloth to make 1 big flag
= 66.84 ÷ 8
= 8.355 m
(b)
Number of remaining big flags that Luis needed
= 8 - 5
= 3
Length of cloth that he was short of
= Length of 3 big flags
= 3 x 8.355
= 25.065 m
Answer(s): (a) 8.355 m; (b) 25.065 m
