Answer:
4) Volume model = 1723 ft³
5) The percentage of the original tank is 51200% of the mock-up
Step-by-step explanation:
4) ∵ The volume of the main tank is 882,158 ft³
∵ The dimension of the scale model is 1/8 of the original model
∵ V model/v original = (dimension model/dimension original)³
∴ Volume model/882,158 = (1/8)³
∴ Volume model = (1/512) × 882,158 = 1722.965 = 1723 ft³
5) The percentage of the original tank is
(882158/1722.965) × 100% = 51200%
12/7. You put the numbers into mixed numbers giving you 18/7 and 9/6. For division you flip the second fraction and multiply them together. So you do 18/7 x 6/9. You're also able to cross cancel 18 and 9 giving you 2/7 x 6/1. 6 x 2 is 12 and 7 x 1 is 7. Your answer is 12/7.
