1:2

Do you want a quick refresher on the ratio 1:2, some practice problems, or a worked example with a specific total? Here’s a quick guide: - Meaning: For every 1 part of quantity A there are 2 parts of quantity B. - Composition: Total parts = 1 + 2 = 3 parts. - Fractions: A = 1/3 of the total, B = 2/3 of the total. - If you know the total T: - A = T/3 - B = 2T/3 Quick examples: - If A:B = 1:2 and total is 90 units, A = 90/3 = 30, B = 2×30 = 60. - If a solution is 1:2 and total volume is 150 ml, A = 50 ml, B = 100 ml. - If A = 12 (and A:B = 1:2), then B = 24. Practice problems (quick to check): 1) A:B = 1:2. If A = 7, what is B? 2) A:B = 1:2. If the total is 30, what are A and B? 3) A:B = 1:2. A mixture totals 540 ml. How many ml of A and B? If you want, tell me the exact problem type (mixtures, recipes, scaling quantities, etc.) or provide a specific total, and I’ll tailor answers or give step-by-step solutions.
