Answer 1

1)10/3+31/6=20+31/6=51/6 2)51/6•2/5=51/15 3)3/2-3/5=15-4/10=11/10 4)11/4•10/11=5/2 5)51/15-51/2=51/6=8,5

Answer 2

Давайте решим эти математические выражения по порядку.

Решение первого выражения:

1) Начнем с упрощения выражения внутри скобок: (+3 + 1/3 + 5/1/6) = 3 + 1/3 + 5 × 6/1 = 3 + 1/3 + 30 = 33 1/3

2) Затем умножим полученное значение на 2/5: 33 1/3 × 2/5 = (33 × 5 + 1) / (3 × 5) = 166/15

3) Вычтем 2: 166/15 - 2 = (166 - 2 × 15) / 15 = (166 - 30) / 15 = 136/15

4) Поделим на (1 + 1/2 - 2/5): 136/15 ÷ (1 + 1/2 - 2/5) = 136/15 ÷ (10/10 + 5/10 - 4/10) = 136/15 ÷ 11/10 = 136/15 × 10/11 = 1360/165 = 272/33

Ответ: 272/33.

Решение второго выражения:

1) Начнем с умножения и деления внутри скобок: 8/15 × 3/17 = 24/255 = 8/85

2) Затем умножим 2 на 8/15 и 2/5 на (2 - 4 + 8/15 × 3/17): 3 + 1/3 × 2 + 2/5 × (2 - 4 + 8/15 × 3/17) = 3 + 1/3 × 2 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3 + 2/3 + 2/5 × (2 - 4 + 8/85) = 3
