Answer 2

А)0,5х2,705х0,2= 0,2705
Б)0,25х(73,8х4)= 73,8
В)(0,8х40,7)х1,25= 40,7
Г)0,79х4,13+4,13х1,21= 8,26

Answer 3

Let's solve each expression step by step:

A) 0.5 x 2.705 x 0.2

Step 1: Multiply 0.5 by 2.705 0.5 x 2.705 = 1.3525

Step 2: Multiply the result by 0.2 1.3525 x 0.2 = 0.2705

So, the result of A) is 0.2705.

B) 0.25 x (73.8 x 4)

Step 1: Multiply 73.8 by 4 73.8 x 4 = 295.2

Step 2: Multiply the result by 0.25 295.2 x 0.25 = 73.8

So, the result of B) is 73.8.

C) (0.8 x 40.7) x 1.25

Step 1: Multiply 0.8 by 40.7 0.8 x 40.7 = 32.56

Step 2: Multiply the result by 1.25 32.56 x 1.25 = 40.7

So, the result of C) is 40.7.

D) 0.79 x 4.13 + 4.13 x 1.21

Step 1: Multiply 0.79 by 4.13 0.79 x 4.13 = 3.2667 (rounded to four decimal places)

Step 2: Multiply 4.13 by 1.21 4.13 x 1.21 = 4.9933 (rounded to four decimal places)

Step 3: Add the two results together 3.2667 + 4.9933 = 8.26 (rounded to two decimal places)

So, the result of D) is 8.26.

To summarize: A) 0.5 x 2.705 x 0.2 = 0.2705 B) 0.25 x (73.8 x 4) = 73.8 C) (0.8 x 40.7) x 1.25 = 40.7 D) 0.79 x 4.13 + 4.13 x 1.21 = 8.26
