Basic Mathematics QUESTION #2820
Question 1
If \(a : b = 3 : 4\) and \(b : c = 6 : 7\), find \(a : b : c\).
  • 9:12:14✔️
  • 3:04:07
  • 6:08:07
  • 3:06:07
Correct Answer Explanation
\(a:b = 3:4\) and \(b:c = 6:7\). Make \(b\) common: \(b = \text{LCM}(4,6) = 12\). \(a:b = 9:12\) and \(b:c = 12:14\). So \(a:b:c = 9:12:14\).
