Question

. 36 +60 :4.2+ 3442 + 54:3.2-18(760 + 100) - (430 + 230)(970-340) + (250 + 120)​

Answer 1

Ответ:

$1)36 + 60 \div 4.2 + 34 = 74 \frac{2}{7} \\ 60 \div 4.2 = 600 \div 42 = 14 \frac{12}{42} = 4 \frac{2}{7} \\ 36 + 4 \frac{2}{7} = 40 \frac{2}{7} + 34 = 74 \frac{2}{7}$

$2)42 + 54 \div 3.2 - 18 = 40 \frac{9}{16} \\ 54 \div 3.2 = 540 \div 32 = 16 \frac{18}{32} = 16 \frac{9}{16 } \\ 42 + 16 \frac{9}{16} = 58 \frac{9}{16} - 18 = 40 \frac{9}{16}$

$3)(760 + 100) - (430 + 230) = 860 - 660 = 200$

$4)630 + 370 = 1000$

Answer 2

Let's break down the given expression step by step:

1. 36 + 60 = 96
2. 4.2 + 3442 = 3446.2
3. 54 : 3.2 = 16.875
4. 18 * (760 + 100) = 14760
5. 430 + 230 = 660
6. 970 - 340 = 630
7. (430 + 230) * (970 - 340) = 413100
8. 250 + 120 = 370

Now, putting it all together:

96 + 3446.2 + 16.875 - 14760 - 660 + 413100 + 370 = 405608.075

So, the value of the given expression is approximately 405608.075.
