Question

2,7×(3,1-2,9)+6,4÷0,8=

Answer 1

Ответ:

8,54

Пошаговое объяснение:

1) 3,1-2,9=0,2

2) 2,7×0,2=0,54

3) 6,4÷0,8=8

4)0,54+8=8,54

Answer 2

To solve the expression, let's perform the operations step by step:

2,7 × (3,1 - 2,9) + 6,4 ÷ 0,8

First, subtract 2.9 from 3.1:

3.1 - 2.9 = 0.2

Next, multiply 2.7 by the result:

2.7 × 0.2 = 0.54

Now, let's divide 6.4 by 0.8:

6.4 ÷ 0.8 = 8

Finally, add the two previous results together:

0.54 + 8 = 8.54

Therefore, the value of the expression 2,7 × (3,1 - 2,9) + 6,4 ÷ 0,8 is 8.54.
