Question

4,4×(10 4/5:5-6,125×1/5+3/8×0,08)

Answer 1

1) 10 4/5 / 5 = 54/5 / 5 = 54/25   ;   2) 6,125 * 1/5 = 6 1/8 * 1/5 = 49/8 * 1/5 = 49/40  ;    3) 3/8 * 0,08 = 3/8 * 8/100 = 3/8 * 2/25 = 6/200 = 3/100 ;

4) 54/25 - 49/40 + 3/100 = 232/200 - 392/200 + 6/200 =  - 154/200 = - 77/100    ;  5) 4,4 * (- 77/100) = 44/10 * (- 77/100) = - 3388/1000 = - 3,388

Answer 2

$4.4 \times (10 \frac{4}{5} \div 5 - 6.125 \times \frac{1}{5} + \frac{3}{8} \times 0.08)$
Будем делать по действиям:
$1) \\ 10 \frac{4}{5} \div 5 = \frac{54}{5} \div \frac{5}{1} = \frac{54}{5} \times \frac{1}{5} = \frac{54}{25}$
$2) \\ 6.125 \times \frac{1}{5} = 6 \frac{125}{1000} \times \frac{1}{5} = 6 \frac{125}{5000} = 6 \frac{1}{40}$
$3) \\ \frac{3}{8} \times 0.08 = \frac{3}{8} \times \frac{8}{100} = \frac{3 \times 8}{8 \times 100} = \frac{3 \times 1}{1 \times 100} = \frac{3}{100}$
$4)\\ 2 \frac{4}{25} - 6 \frac{1}{40} = 2 \frac{32}{200} - 6 \frac{5}{200} = \frac{432}{200} - \frac{1205}{200} = - \frac{773}{200} = - 3 \frac{173}{200}$
$5) \\ - 3 \frac{173}{200} + \frac{3}{100} = - 3 \frac{173}{200} + \frac{6}{200} = - 3 \frac{167}{200}$

Время истекло, пишу как могу

$6) \\ 4.4 \times - 3 \frac{173}{200} = 4 \frac{4}{10} - 3 \frac{173}{200} = - \frac{44 \times 767}{10 \times 200} = \frac{11 \times 767}{10 \times 50} = \frac{8437}{500}$

Answer 3

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division, and Addition and Subtraction:

1. Start with the operations inside the parentheses: 10 4/5 = 10.8 (10 divided by 5, then add 4) 6,125 × 1/5 = 1.225 (6.125 multiplied by 1/5) 3/8 × 0.08 = 0.03 (3 divided by 8, then multiplied by 0.08)

2. Replace the expression with the calculated values: 4 × (10.8 - 1.225 + 0.03)

3. Perform the subtraction: 10.8 - 1.225 + 0.03 = 9.605

4. Continue with the multiplication: 4 × 9.605 = 38.42

So, the final result of the expression is 38.42.
