Answer 1

Из двух дробей с одинаковыми знаменателями больше та, у которой числитель больше:

$\frac{5}{9} > \frac{4}{9} \\ \frac{1}{8} < \frac{7}{8} \\ \frac{2}{5} < \frac{3}{5} \\ \frac{2}{7} < \frac{6}{7}$

Answer 2

А) 5/9 * 4/9: To solve this multiplication of fractions, you simply multiply the numerators (top numbers) together and the denominators (bottom numbers) together. So, for 5/9 * 4/9, the calculation would be (5 * 4) / (9 * 9). This simplifies to 20/81. Therefore, the answer is 20/81.

Б) 1/8 * 7/8: Similarly, for 1/8 * 7/8, the calculation would be (1 * 7) / (8 * 8). This simplifies to 7/64. Therefore, the answer is 7/64.

В) 2/5 * 3/5: For 2/5 * 3/5, the calculation would be (2 * 3) / (5 * 5). This simplifies to 6/25. Therefore, the answer is 6/25.

Г) 2/7 * 6/7: Lastly, for 2/7 * 6/7, the calculation would be (2 * 6) / (7 * 7). This simplifies to 12/49. Therefore, the answer is 12/49.
