Answer 1

Пошаговое объяснение:

1)900:180=5

168:56*420:30=42

600:120*1000:3600=1,389

2)5+42+1,389=48,389

Answer 2

Ответ:

45.61

Пошаговое объяснение:

900÷180=5 168÷56=3

3•420=1260 1260÷30=42

600÷120=5 5•1000=5000 5000÷3600=1.39~ 5+42=47 47-1.39=45.61

Answer 3

To solve this expression, we need to follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

Let's break down the expression step by step:

1. 900 ÷ 180 = 5
2. 168 ÷ 56 = 3
3. 3 × 420 = 1260
4. 420 ÷ 30 = 14
5. 600 ÷ 120 = 5
6. 5 × 1000 = 5000
7. 5000 ÷ 3600 ≈ 1.388 (rounded to three decimal places)

Now, we can perform the remaining operations:

5 + 1260 - 14 - 1.388 ≈ 1249.612

Therefore, the result of the expression is approximately 1249.612.
