Will needed exactly 82 m of cloth to make 17 small identical flags and 7 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 17 small flags + Length of 7 big flags = 82 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 17 small flags
= 17 x 1.305
= 22.185 m
Length of cloth for 7 big flags
= 82 - 22.185
= 59.815 m
Length of cloth to make 1 big flag
= 59.815 ÷ 7
= 8.545 m
(b)
Number of remaining big flags that Will needed
= 7 - 3
= 4
Length of cloth that he was short of
= Length of 4 big flags
= 4 x 8.545
= 34.18 m
Answer(s): (a) 8.545 m; (b) 34.18 m
