( 2 3/8 + 3 7/24) ÷ (4 2/3 - 1 1/8)
(3,6 - 1 2/3) ÷ ( 4 1/15 - 2 7/9)​

Answer 1

Пошаговое объяснение:

№1

1) 2 3/8 + 3 7/24 = 2 9/24 + 3 7/24 = 5 16/24 = 5 2/3

2) 4 2/3 - 1 1/8 = 4 16/24 - 1 3/24 = 3 13/24

3) 5 2/3 : 3 13/24 = 17/3 : 85/24 = 17/3 * 24/85 = 1/1 * 8/5 = 8/5 = 1 3/5

№2

1) 3,6 - 1 2/3 = 3 6/10 - 1 2/3 = 3 18/30 - 1 20/30 = 2 48/30 - 1 20/30 = 1 28/30 = 1 14/15

2) 4 1/15 - 2 7/9 = 4 3/45 - 2 35/45 = 3 48/45 - 2 35/45 = 1 13/45

3) 1 14/15 : 1 13/45 = 29/15 : 58/45 = 29/15 * 45/58 = 1/1 * 3/2 = 3/2 = 1 1/2
