Question

Найдите значение выражения:
1 5/6+4/5×(3 1/3-1 1/4)

2 1/6:1 1/12+48×(1 1/8-1/12)

Answer 1

Пошаговое объяснение:

№1

1) 3 1/3 - 1 1/4 = 3 4/12 - 1 3/12 = 2 1/12

2) 4/5 * 2 1/12 = 4/5 * 25/12 = 1/1 * 5/3 = 5/3 = 1 2/3

3) 5/6 + 1 2/3 = 5/6 + 1 4/6 = 1 9/6 = 2 3/6 = 2 1/2

№2

1) 1/6 : 1 1/12 = 1/6 : 13/12 = 1/6 * 12/13 = 1/1 * 2/13 = 2/13

2) 1 1/8 - 1/12 = 1 3/24 - 2/24 = 1 1/24

3) 48 * 1 1/24 = 48 * 25/24 = 2 * 25/1 = 50/1 = 50

4) 2/13 + 50 = 50 2/13

Answer 2

Ответ:

Пошаговое объяснение:

1 5/6 + 4/5 * (3 1/3 - 1 1/4) = 3 1/2

1) 3 1/3 - 1 1/4 = 3 4/12 - 1 3/12 = 2 1/12

2) 4/5 * 2 1/12 = 4/5 * 25/12 = 5/3 = 1 2/3

3) 1 5/6 + 1 2/3 = 1 5/6 + 1 4/6 = 2 9/6 = 3 1/2

№2

2 1/6 : 1 1/12 + 48 * (1 1/8 - 1/12) = 52

1) 2 1/6 : 1 1/12 = 13/6 : 13/12 = 13/6 * 12/13 = 2

2) 1 1/8 - 1/12 = 1 3/24 - 2/24 = 1 1/24

3) 48 * 1 1/24 = 48 * 25/24 = 2 * 25/1 = 50

4) 2 + 50 = 52
