Пошаговое объяснение:

13440:32:7+7,123=67.123

1)13440:32=420

2)420:7=60

3)60+7,123=67,123

(1638:39+13284:36):1=133

1)1638:39-42

2)3284:36=91

3)42+91=133

4)133:1=133

509-603-999999:11+3,98=-91006,98

1)999999:11=90909

2)90909+3,98=90912,98

3)509-603=-94

4)-94-90912,98=-91006,98

(21000-308-29):4+14147

1)21000-308-29=20663

2)20664:4=5165,75

3)5165,75+14147=19312,75

Answer 2

I can help you solve the mathematical expression you provided using the order of operations (PEMDAS) which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. Here's the step-by-step solution:

1. Start with the innermost parentheses:

(1 638:39 + 13 284 : 36) = 39.595238 + 368.444444 = 408.039682

(90 050 - 219 - 380 + 190) = 89,641

(302 281 - 12 649) = 289,632

(21 000 – 308 - 29) = 20,663

2. Perform the division and multiplication, from left to right:

13 440:32:7+7.123 = 422.123

408.039682 : 1509 = 0.2700137

89,641 : 11 = 8149.181818

289,632 : 48 = 6034

20,663 : 4 = 5,165.75

90(6034) = 543,060

3966(5165.75) = 20,466,580.5

3. Perform the addition and subtraction, from left to right:

422.123 - 8149.181818 = -7727.058818

-7727.058818 + 543,060 = 535,332.941182

535,332.941182 - 999999 : 11 = 4413.180108

4413.180108 + 20,466,580.5 = 20,470,993.680108

4. Finally, divide 14,147 by the result obtained in step 3:

14,147 : 20,470,993.680108 = 0.0006904023

Therefore, the final answer to the expression you provided is approximately 0.0006904023.
