Will needed exactly 75 m of cloth to make 15 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 126
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 15 small flags + Length of 9 big flags = 75 m
1 m = 100 cm
Length of cloth for each small flag
= 126
12 cm
= 126.5 cm
= 1.265 m
Length of cloth for 15 small flags
= 15 x 1.265
= 18.975 m
Length of cloth for 9 big flags
= 75 - 18.975
= 56.025 m
Length of cloth to make 1 big flag
= 56.025 ÷ 9
= 6.225 m
(b)
Number of remaining big flags that Will needed
= 9 - 5
= 4
Length of cloth that he was short of
= Length of 4 big flags
= 4 x 6.225
= 24.9 m
Answer(s): (a) 6.225 m; (b) 24.9 m
