Пошаговое объяснение:

2 1/6 + 1 1/9•3/10= 2 1/6 + 10/9 * 3/10 = 2 1/6 + 1/3 = 2 1/6 + 2/6 = 2 3/6 = 2 1/2

6 2/3•1 5/16 -3 9/14 = 20/3 * 21/16 - 3 9/14 = 35/4 - 3 9/14 = 8 3/4 - 3 9/14 =

= 8 21/28 -3 18/28 = 5 3/28

10 19/30 -3 5/9• 2 7/10 = 10 19/30 - 32/9 * 27/10 = 10 19/30 - 48/5 =

= 10 19/30 - 9 3/5 = 10 19/30 - 9 18/30 = 1 1/30

Answer 2

Пошаговое объяснение:

№1

1) 1 1/9 * 3/10 = 10/9 * 3/10 = 1/3 * 1/1 = 1/3

2) 2 1/6 + 1/3 = 2 1/6 + 2/6 = 2 3/6 = 2 1/2

№2

1) 6 2/3 * 1 5/16 = 20/3 * 21/16 = 5/1 * 7/4 = 35/4 = 8 3/4

2) 8 3/4 - 3 9/14 = 8 21/28 - 3 18/28 = 5 3/28

№3

1) 3 5/9 * 2 7/10 = 32/9 * 27/10 = 16/1 * 3/5 = 48/5 = 9 3/5

2) 10 19/30 - 9 3/5 = 10 19/30 - 9 18/30 = 1 1/30
