Answer 1

(25×2400+66000):70-(52×550-107×140):20=(60000+66000):70-(28600-14980):20=126000:70-13620:70=1800-681=1119

Answer 2

Ответ:

1119

Объяснение:

(25×2400+66000):70-(52×550-107×140):20 = (60000 + 66000) ÷ 70 - (28600 - 14980) ÷ 20 = 126000 ÷ 70 - 13620 ÷ 20 = 1800 - 681 = 1119

Answer 3

To solve the given expression, let's break it down step by step:

1. Simplify the expression inside the parentheses first: (52×550-107×140)

- Multiply 52 by 550: 52 × 550 = 28600 - Multiply 107 by 140: 107 × 140 = 14980 - Subtract the second result from the first: 28600 - 14980 = 13620

So, the expression inside the parentheses simplifies to 13620.

2. Simplify the expression outside the parentheses next: (25×2400+66000):70

- Multiply 25 by 2400: 25 × 2400 = 60000 - Add 60000 to 66000: 60000 + 66000 = 126000 - Divide 126000 by 70: 126000 ÷ 70 = 1800

So, the expression outside the parentheses simplifies to 1800.

3. Now, substitute the simplified values back into the original expression: 1800 - 13620 : 20

- Divide 13620 by 20: 13620 ÷ 20 = 681

So, the final result of the expression (25×2400+66000):70-(52×550-107×140):20 is 681.
