Question

64 : (2,75 + 0,45) — 4,8

Answer 1

Ответ:

15,2

Пошаговое объяснение:

1) 2,75+0,45=3,2.

2) 64:3,2=20.

3) 20-4,8=15,2

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. First, calculate the sum inside the parentheses: 2.75 + 0.45 = 3.20

2. Then, calculate the expression inside the parentheses: 3.20 - 4.8 = -1.60

3. Finally, divide 64 by the result from step 2: 64 / (-1.60) = -40

So, 64 : (2.75 + 0.45) - 4.8 = -40.
