3:1

Nice—3:1 is a ratio. Here’s a quick refresher:

• Meaning: For every 4 parts total, 3 parts are of the first thing and 1 part of the second.
• Fractions of total: first part = 3/4 of the total, second part = 1/4 of the total.
• If total amount is T:
  • Quantity A = (3/4) T
  • Quantity B = (1/4) T
• If you know one part, the other is three times or one third of it:
  • A = 3B, or B = A/3
• Percentages: A = 75%, B = 25%.
• Example: If you have 12 units in total, A = 9 and B = 3.

If you have a specific problem (e.g., “mix 3 parts A with 1 part B to make 40 units”), share the exact numbers and I’ll solve it step by step.
