Решение
1) 5 * (2/3 * 6 + 1/5) / (2 * 1/2 + 4 1/4) = 5 * (4 + 1/5) / (1 + 4 1/4) = (5 * 4 1/5) / (5 1/4) = 21/(21/4) = 4*21/21 = 4 * 1 = 4
2) 3 * (8.31 – 2.29) / (2 * 2.01 + 2) – 1 = 3 * 6.02 / (4.02 + 2) – 1 = 3 * 6.02 / 6.02 – 1 = 3 * 1 – 1 = 3 – 1 = 2
2) 3 * (8.31 – 2.29) / (2 * 2.01 + 2) – 1 = 3 * 6.02 / (4.02 + 2) – 1 = 3 * 6.02 / 6.02 – 1 = 3 * 1 – 1 = 3 – 1 = 2
1) 5 * (2/3 * 6 + 1/5) / (2 * 1/2 + 4 1/4) = 5 * (4 + 1/5) / (1 + 4 1/4) = (5 * 4 1/5) / (5 1/4) = 21/(21/4) = 4*21/21 = 4 * 1 = 4
2) 3 * (8.31 – 2.29) / (2 * 2.01 + 2) – 1 = 3 * 6.02 / (4.02 + 2) – 1 = 3 * 6.02 / 6.02 – 1 = 3 * 1 – 1 = 3 – 1 = 2
2) 3 * (8.31 – 2.29) / (2 * 2.01 + 2) – 1 = 3 * 6.02 / (4.02 + 2) – 1 = 3 * 6.02 / 6.02 – 1 = 3 * 1 – 1 = 3 – 1 = 2
