KnowledgeBoat · Accepted Answer

(i) 30, 40, 45, 60 The given numbers are 30, 40, 45, 60. We have: ∴ (30 : 40) = (45 : 60) Hence, 30, 40, 45 and 60 are in proportion. (ii) The given numbers are . Convert mixed to improper fraction: We have: . Hence, are not in proportion. (iii) 0.8, 3, 2.4, 9 The given numbers are 0.8, 3, 2.4, 9. Multiply by 10 to convert decimals to whole numbers: We have: ∴ (0.8 : 3) = (2.4 : 9) Hence, 0.8, 3, 2.4 and 9 are in proportion. (iv) The given numbers are . We have: Hence, are not in proportion. (v) The given numbers are . We have: . Hence, are in proportion.
