3:4

3:4 is a simple ratio meaning A is 3 parts and B is 4 parts.

Key conversions:

• As a fraction of the total (A+B = 7 parts): A = 3/7 of the total, B = 4/7 of the total.
• If the total quantity is x, then A = (3/7)x and B = (4/7)x.
• Decimal/percentage of the total: A portion = 3/7 ≈ 0.4286 (≈ 42.86%), B portion = 4/7 ≈ 0.5714 (≈ 57.14%).
• If you know one part, you can scale: 1 part = total/7.
  • Example: If B = 56, then 4 parts = 56 → 1 part = 14 → A = 3×14 = 42.

Simple examples:

• If the total is 21 units: A = 9, B = 12.
• If B is 56 units: A is 42 units.
