2:3

2:3 is a ratio. It means two parts of something (A) for every three parts of something else (B).

Key points:

• There exists a common multiplier k with A = 2k and B = 3k.
• Total parts = 2 + 3 = 5, so if the whole quantity is Q, then A = (2/5)Q and B = (3/5)Q.
• As a fraction, A:B = 2:3 implies A/B = 2/3.
• As percentages of the total Q: A = 40% of Q, B = 60% of Q.

Examples:

• If the total is 50 units: A = 2/5 × 50 = 20, B = 3/5 × 50 = 30.
• If B = 9, then k = 3 (since 3k = 9), so A = 2k = 6 and B = 9.
• If A = 22 and A:B = 2:3, then k = 11, so B = 3k = 33.
