Answer 1

Ответ:

Пошаговое объяснение:

№1

5 - 3/(4 + 1/2) = 5 - 3/(4. 1/2) =

5 - 3/(9/2) = 5 - 3 * 2/9 = 5 - 6/9 =

5 - 2/3 = 4. 3/3 - 2/3 = 4. 1/3

№2

3 + 4/(1-1/3) = 3 + 4/(2/3) =

3 + 4 * 3/2 = 3 + 12/2 = 3 + 6 = 9

№3

6 - 5/(3-1/2) = 6 - 5/(2. 1/2) =

6 - 5/(5/2) = 6 - 5 * 2/5 = 6 - 10/5 =

6 - 2 = 4

№4

2/5 + 4/(6+2/3) = 2/5 + 4/(6. 2/3) =

2/5 + 4/(20/3) = 2/5 + 4 * 3/20 =

2/5 + 12/20 = 2/5 + 3/5 = 5/5 = 1
