Caden needed exactly 82 m of cloth to make 15 small identical flags and 7 big identical flags. He had some cloth which was just enough to make all the small flags and 5 big flags. He used 125
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 7 big flags = 82 m
1 m = 100 cm
Length of cloth for each small flag
= 125
12 cm
= 125.5 cm
= 1.255 m
Length of cloth for 15 small flags
= 15 x 1.255
= 18.825 m
Length of cloth for 7 big flags
= 82 - 18.825
= 63.175 m
Length of cloth to make 1 big flag
= 63.175 ÷ 7
= 9.025 m
(b)
Number of remaining big flags that Caden needed
= 7 - 5
= 2
Length of cloth that he was short of
= Length of 2 big flags
= 2 x 9.025
= 18.05 m
Answer(s): (a) 9.025 m; (b) 18.05 m
