But $ \frac{144}{256} = \frac{9}{16} $? $144 \div 16 = 9$, $256 \div 16 = 16$, but $16 \times 16 = 256$, $16 \times 9 = 144$, yes. But $ \frac{144}{256} = \frac{144 \div 16}{256 \div 16} = \frac{9}{16} $, correct.

["Proving $ \frac{144}{256} = \frac{9}{16} $: A Step-by-Step Breakdown", "Understanding how fractions simplify is essential for mastering math basics. One clear and elegant way to verify $ \frac{144}{256} = \frac{9}{16} $ lies in simplifying both the numerator and denominator by their greatest common divisor (GCD).

The GCD of 144 and 256 is 16. This means both numbers are divisible by 16 without leaving a remainder:\n- $ 144 \div 16 = 9 $\n- $ 256 \div 16 = 16 $", "Since both results are whole numbers, we can safely write:\n$$\n\frac{144}{256} = \frac{144 \div 16}{256 \div 16} = \frac{9}{16}\n$$", "### Step 2: Why $ 16 \ imes 9 = 144 $ and $ 16 \ imes 16 = 256 $", "A full validation confirms the correctness:\n- $ 16 \ imes 9 = 144 $ — correct, since $ 10 \ imes 16 = 160 $, minus $ 1 \ imes 16 = 16 $, gives 144.\n- $ 16 \ imes 16 = 256 $ — obvious from power of 16.", "These multiplications confirm that 144 and 256 are exactly 9 and 16 times 16, respectively. Hence, dividing numerator and denominator by 16 preserves the ratio exactly.", "### The Full Simplification", "Alternatively, we can simplify step by step:\n$$\n\frac{144}{256} = \frac{144 \div 16}{256 \div 16} = \frac{9}{16}\n$$\nThen verify $ \frac{9}{16} $ — this is already in lowest terms (9 and 16 share no common divisors other than 1).", "### Why This Method Is Powerful", "Simplifying fractions by dividing numerator and denominator by the same non-zero number is a foundational skill.
