Answer 1

Пошаговое объяснение:

Все действия выполняем слева направо . сначала выполняем действия в скобках , затем умножение/деление , затем сложение /вычитание.

а) 7,3 * 12 +102,14 * 100 = 87,6 + 10 214 =10301,6

б) 10 * 0,07 * 31 + 8,3 = 0,7 * 31 + 8,3 = 21,7 + 8,3 = 30

в) 703,12 * 4 * 10,7 * 10 000= 2812,48 * 10,7 * 10000 = 30093,536 * 10000=  =300 935 360

г) 17,12 *0,1 * 10 = 17,12 * ( 0,1*10) = 17,12 * 1= 17,12

Answer 2

It seems like you have provided a series of mathematical expressions with various operations (addition and multiplication) involving decimals and integers. Let's calculate each of these expressions step by step:

A) 7.3 x 12 + 102.14 x 100: First, perform the multiplications: 7.3 x 12 = 87.6 102.14 x 100 = 10214

Now, add the results together: 87.6 + 10214 = 10301.6

So, A) 7.3 x 12 + 102.14 x 100 = 10301.6

5. 10 x 0.07 x 31 + 8.3: First, perform the multiplications: 10 x 0.07 = 0.7 0.7 x 31 = 21.7

   Now, add 21.7 to 8.3: 21.7 + 8.3 = 30

So, 5) 10 x 0.07 x 31 + 8.3 = 30

B) 703.12 x 4 x 10.7 x 10000: First, perform the multiplications: 703.12 x 4 = 2812.48 2812.48 x 10.7 = 30145.296 30145.296 x 10000 = 301452960

So, B) 703.12 x 4 x 10.7 x 10000 = 301452960

R) 17.12 x 0.1 x 10: First, perform the multiplications: 17.12 x 0.1 = 1.712 1.712 x 10 = 17.12

So, R) 17.12 x 0.1 x 10 = 17.12
