Langkah 1 Let’s denote the number of red marbles as R, yellow marbles as Y, and green marbles as G. Langkah 2 From the given information, we know that R + Y + G = 12 (total number of marbles). Langkah 3 It is also given that R = 1/2 * (R + Y + G) = 1/2 * 12 = 6. Langkah 4 Given that Y > G, we can assume Y = G + x, where x is a positive integer. Langkah 5 Substituting the values of R and Y into the equation R + Y + G = 12, we get 6 + (G + x) + G = 12. Langkah 6 Simplifying the equation, we get 2G + x = 6. Langkah 7 Since the number of marbles is a whole number, we can try different values of x to find a solution that satisfies the equation. Langkah 8 By trying x = 2, we get 2G + 2 = 6, which gives G = 2. Langkah 9 Substituting G = 2 back into Y = G + x, we get Y = 2 + 2 = 4. Langkah 10 Therefore, the number of red marbles is 6, yellow marbles is 4, and green marbles is 2. Jawaban 6 red marbles, 4 yellow marbles, 2 green marbles
