Пошаговое объяснение:

(6целых 2/3 + 3целых 1/8) - (12 - 10целых 5/9)

1) 6целых 2/3 + 3целых 1/8 = 6целых 16/24 + 3целых 3/24 = 9целых 19/24

2) 12 - 10целых 5/9 = 11целых 9/9 - 10целых 5/9 = 1целая 4/9

3) 9целых 19/24 - 1целая 4/9 = 9целых 57/72 - 1целая 32/72 = 8целых 25/72

Answer 3

To solve the expression (6 2/3 + 3 1/8) - (12 - 10 5/9), follow these steps:

Step 1: Convert all mixed numbers to improper fractions. Step 2: Perform the operations inside the parentheses. Step 3: Perform the subtraction.

Let's start:

Step 1: Convert mixed numbers to improper fractions 6 2/3 = (6 * 3 + 2) / 3 = 20/3 3 1/8 = (3 * 8 + 1) / 8 = 25/8 12 = 12 10 5/9 = (10 * 9 + 5) / 9 = 95/9

Step 2: Evaluate the expression inside the parentheses (20/3 + 25/8) - (12 - 95/9)

Step 3: Perform the addition and subtraction To add 20/3 and 25/8, we need to find a common denominator, which is 24.

20/3 = (20/3) * (8/8) = 160/24 25/8 = (25/8) * (3/3) = 75/24

Now, we can perform the addition: 160/24 + 75/24 = (160 + 75) / 24 = 235/24

Now, we can subtract the remaining numbers: 235/24 - (12 - 95/9)

To subtract 12 from 235/24, we need to convert 12 to the same denominator, which is 24.

12 = (12/1) * (24/24) = 288/24

Now, we can perform the subtraction: 235/24 - 288/24 = (235 - 288) / 24 = -53/24

Finally, we need to subtract 95/9 from -53/24, and we also need to find a common denominator, which is 24:

95/9 = (95/9) * (8/8) = 760/72

Now, we can perform the subtraction: -53/24 - 760/72 = (72*(-53) - 24*760) / 72 = (-3816 - 18240) / 72 = -22056/72 = -307/1

So, the final result is -307.
