Japheth needed exactly 89 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 3 big flags. He used 130
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 = 89 m
1 m = 100 cm
Length of cloth for each small flag
= 130
12 cm
= 130.5 cm
= 1.305 m
Length of cloth for 16 small flags
= 16 x 1.305
= 20.88 m
Length of cloth for 8 big flags
= 89 - 20.88
= 68.12 m
Length of cloth to make 1 big flag
= 68.12 ÷ 8
= 8.515 m
(b)
Number of remaining big flags that Japheth needed
= 8 - 3
= 5
Length of cloth that he was short of
= Length of 5 big flags
= 5 x 8.515
= 42.575 m
Answer(s): (a) 8.515 m; (b) 42.575 m
