Answer 2

Переводим смешанные дроби в неправильные и решаем:

1) $\frac{109}{13} * \frac{64}{11} + \frac{109}{13} * \frac{79}{11} = 109$

1. $\frac{109}{13} * \frac{64}{11} = \frac{6976}{143}$

2. $\frac{109}{13} * \frac{79}{11} = \frac{8611}{143}$

3. $\frac{6976}{143} + \frac{8611}{143} = \frac{15587}{143} = 109$

2) $\frac{43}{8} * \frac{3}{2} - \frac{3}{2} * \frac{41}{8} = 0,375$

1. $\frac{43}{8} * \frac{3}{2} = \frac{129}{16}$

2. $\frac{3}{2} * \frac{41}{8} = \frac{123}{16}$

3. $\frac{129}{16} - \frac{123}{16} = \frac{6}{16} = 0,375$

3) $(11 - 5\frac{2}{9}) * 9 = 52$

1. $10\frac{9}{9} - 5\frac{2}{9} = 5\frac{7}{9}$

2. $\frac{52}{9} * \frac{9}{1} = 52$

Answer 3

To solve the given expression, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses E: Exponents MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Let's go step by step:

Step 1: Perform multiplication and division from left to right. 8 5/13 * 5 9/11 = 8.384615 * 5.818182 ≈ 48.762701

8 5/13 * 7 2/11 5 3/8 = 8.384615 * 7.181818 ≈ 60.369074

1 1/2 - 1 1/2 * 5 1/8 = 1.5 - 1.125 ≈ 0.375

Step 2: Solve the expression inside the parentheses. (11 - 5 2/9) * 9 = (11 - 5.2222) * 9 ≈ 50

Step 3: Perform the remaining multiplication and division. 48.762701 + 60.369074 ≈ 109.131775

109.131775 * 0.375 ≈ 40.920666875

So, the final result of the expression is approximately 40.920666875.
