6. Виконай вiднiмання: 1)7/12-3/8 2)3 4/9-1 2/3 будь ласка допоможіть​

Answer 1

Ответ:

Звіднімаймо:

1) 7/12 - 3/8

Спочатку знайдемо спільний знаменник, який буде 24. Потім віднімемо:

(7/12) - (9/24) = (7/12) - (3/8) = (14/24) - (9/24) = 5/24

2) 3 4/9 - 1 2/3

Спочатку переведемо змішані числа в неправильні дроби:

3 4/9 = (3 * 9 + 4) / 9 = (27 + 4) / 9 = 31/9

1 2/3 = (1 * 3 + 2) / 3 = (3 + 2) / 3 = 5/3

Тепер віднімемо:

(31/9) - (5/3) = (31/9) - (15/9) = (31 - 15) / 9 = 16/9

Отже, відповіді:

1) 7/12 - 3/8 = 5/24

2) 3 4/9 - 1 2/3 = 16/9

Answer 2

1)14/24-9/24=5/24 ;2)34/9-36/9=-2/9

Answer 3

1) Виконай віднімання: 7/12 - 3/8

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 24.

Converting the fractions to have a denominator of 24: 7/12 = 14/24 3/8 = 9/24

Now, we can subtract the fractions: 14/24 - 9/24 = 5/24

Therefore, the result of the subtraction 7/12 - 3/8 is 5/24.

2) Виконай віднімання: 3 + 4/9 - 1 + 2/3

To add or subtract mixed numbers, we need to convert them to improper fractions.

Converting the mixed numbers to improper fractions: 3 = 27/9 1 = 9/9

Now, we can add or subtract the fractions: 27/9 + 4/9 - 9/9 + 2/3 = (27 + 4 - 9)/9 + 2/3 = 22/9 + 2/3

To add or subtract fractions, we need to have a common denominator. In this case, the common denominator is 9.

Converting the fractions to have a denominator of 9: 22/9 = 22/9 2/3 = 6/9

Now, we can add the fractions: 22/9 + 6/9 = 28/9

Therefore, the result of the subtraction 3 + 4/9 - 1 + 2/3 is 28/9.
