Answer/Step-by-step Explanation:
==>Given:
Ratio of cost of 1m polyester fabric to 1m of cotton fabric = 2:7
I.e. if 1m of polyester fabric = £2, then 1m of cotton fabric = £7.
==>Required:
a. Cost of polyester fabric for the following lengths:
i) 6m ii) 8m iii) 9m
Thus, having known that cost of 1m polyester fabric = £2, therefore,
i) 6m polyester fabric = 6×2 = £12
ii) 8m polyester fabric = 8×2 = £16
iii) 9m polyester fabric = 9×2 = £18
b. Cost 8 cotton fabric for the following lengths:
i) 2m ii) 6m iii) 8m iv) 9m
Thus, since 1m of cotton fabric = £7, therefore,
i) 2m cotton fabric = 2×7 = £14
ii) 6m cotton fabric = 6×7 = £42
iii) 8m cotton fabric = 8×7 = £56
iv) 9m cotton fabric = 9×7 = £63
