Question

Найдите разность. 4/9-(-1/6)=... -5/8-(-7/10)=... 7/12-17/18=... -9/20-4/15=... 3/10-8/15=... -11/25-(-3/10)=...

Answer 1

Ответ:

1. 11/18

2. 3/40

3. -13/36

4. -43/60

5. -7/30

6. -7/50

Пошаговое объяснение:

1. 4/9 - (-1/6) = 4/9 + 1/6 = 16/36 + 6/36 = 22/36 = 11/18

2. -⅝ - (-7/10) = -⅝ + 7/10 = -25/40 + 28/40 = 3/40

3. 7/12 - 17/18 = 21/36 - 34/36 = -13/36

4. -9/20 - 4/15 = -27/60 - 16/60 = -43/60

5. 3/10 - 8/15 = 9/30 - 16/30 = -7/30

6. -11/25 - (-3/10) = -22/50 + 15/50 = -7/50

Answer 2

Давайте посчитаем разности для данных дробей:

1. (4/9) - (-1/6) = (4/9) + (1/6) = (8/18) + (3/18) = 11/18

2. (-5/8) - (-7/10) = (-5/8) + (7/10) = (-25/40) + (28/40) = 3/40

3. (7/12) - (17/18) = (7/12) - (17/18) = (21/36) - (34/36) = -13/36

4. (-9/20) - (4/15) = (-9/20) - (16/60) = (-27/60) - (16/60) = -43/60

5. (3/10) - (8/15) = (3/10) - (16/30) = (9/30) - (16/30) = -7/30

6. (-11/25) - (-3/10) = (-11/25) + (6/25) = (-5/25) = -1/5

Итак, разности для данных дробей равны:

1. 11/18
2. 3/40
3. -13/36
4. -43/60
5. -7/30
6. -1/5
