If A:B = 2:3 and B:C = 4:5, then A:C =
A8:15 (multiply: A/C = A/B × B/C = (2/3)(4/5) = 8/15)
B2:5
C6:5
D8:15
Answer & Solution
Correct answer: A. 8:15 (multiply: A/C = A/B × B/C = (2/3)(4/5) = 8/15)
To find A:C, make B common. A:B = 2:3 = 8:12. B:C = 4:5 = 12:15. So A:B:C = 8:12:15. Hence A:C = 8:15.
