Question

4×(2 1/2+1 3/4) -(6 2/3+4 4/5) :2​

Answer 1

Ответ:

Пошаговое объяснение:

1) 2. 1/2 + 1. 3/4 =

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

4. 1/4

2) 4 * 4. 1/4 = 4 * 17/4 =

1 * 17/1 = 17/1 = 17

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

6. 10/15 + 4. 12/15 =

10. 22/15 = 11. 7/15

4) 11. 7/15 : 2 = 172/15 : 2 =

172/15 * 1/2 = 86/15 * 1/1 =

86/15 = 5. 11/15

5) 17 - 5. 11/15 =

16. 15/15 - 5. 11/15 = 11. 4/15

Ответ: 11. 4/15

Answer 2

4×(2+1/2+1+3/4) = 4×(2+0.5+1+0.75) = 4×(3.25) = 13

-(6+2/3+4+4/5) = -(6+0.67+4+0.8) = -(11.47) ≈ -11.47

13 - 11.47 ÷ 2 = 13 - 5.735 = 7.265

Итак, результат выражения 4×(2+1/2+1+3/4)+-(6+2/3+4+4/5)+:2 равен 7.265.
