Sagot :
- 6:9 = 8:12
(Solution)
12×6 = 72
72÷8 = 9
(Re-check)
Multiply both the means and both extremes. Their product should be the same since the two ratio is porportional to each other. If they won't have the same product, then you made a mistake.
[Means: 9 & 8]
[Extremes: 6 & 12]
6×12 = 72
9×8 = 72
