Answer 1

Ответ:

1)-14,8,40

2)67,9

3)48

Answer 2

Let's solve each of these math expressions step by step:

1. 0.2 - 15.8 × 5: First, we'll perform the multiplication: 15.8 × 5 = 79

Now, subtract this result from 0.2: 0.2 - 79 = -78.8

So, the answer is -78.8.

2. (6.79 × 2.5) × 4: First, we'll calculate the product inside the parentheses: 6.79 × 2.5 = 16.975

Now, multiply this result by 4: 16.975 × 4 = 67.9

So, the answer is 67.9.

3. 4.8 × 7.8 + 4.8 × 2.2: First, calculate the two products separately: 4.8 × 7.8 = 37.44 4.8 × 2.2 = 10.56

Now, add these two results together: 37.44 + 10.56 = 48

So, the answer is 48.
