If a = b : 2 and b : c = 4 : 3, then find a : b : c

🧠 Explanation:

If a = b : 2 and b : c = 4 : 3, then a : b : c is 8 : 12 : 9. To find this, express b as 2a from the first ratio, then use b = 4k and c = 3k from the second. So, a : b : c = 2k : 4k : 3k = 8 : 12 : 9 (using a common multiplier). This helps students learn ratio calculations, useful in math and science.
