2)1³¹/³²•3⅕+(8⁵/⁹•⁶/³⁵+3⁸/¹⁵)•⁷/⁵⁰=

Answer 1

Пошаговое объяснение:

№1

1) 4 1/7 * 14 = 29/7 * 14 = 29/1 * 2 = 58/1 = 58

2) 1 1/4 * 1 1/6 = 5/4 * 7/6 = 35/24 = 1 11/24

3) 1 2/9 * 2 5/8 = 11/9 * 21/8 = 231/72 = 3 15/72

4) 58 - 1 11/24 - 3 15/72 = 57 72/72 - 1 33/72 - 3 15/72 = 53 24/72 = 53 1/3

№2

1) 8 5/9 * 6/35 = 77/9 * 6/35 = 11/3 * 2/5 = 22/15 = 1 7/15

2) 1 7/15 + 3 8/15 = 4 15/15 = 5

3) 5 * 7/50 = 35/50 = 7/10

4) 1 31/32 * 3 1/5 = 63/32 * 16/5 = 63/2 * 1/5 = 63/10 = 6 3/10

5) 6 3/10 + 7/10 = 6 10/10 = 7
