Answer 1

Ответ:

1) 7 007×428:(81 405 - 81 191) = 7 007×428:214= 7 007×2= 14 014

2) 444×209:(10 105 - 9 957) = 444×209:148= 92 796÷148= 627

3)

Пошаговое объяснение:

344×627: (9 107 - 8 978) = 344×627÷129= 215 688÷129 = 1 672

Answer 2

Let's break down each expression step by step:

1. $7,007 \cdot 428 : (81,405 - 81,191)$ First, we calculate the difference inside the parentheses: $81,405 - 81,191 = 214$ Now, we divide $7,007 \cdot 428$ by 214 to get the result: $7,007 \cdot 428 / 214 = 14,014$

2. $444 \cdot 209 : (10,105 - 9,957)$ Again, we calculate the difference inside the parentheses: $10,105 - 9,957 = 148$ Now, we divide $444 \cdot 209$ by 148 to get the result: $444 \cdot 209 / 148 = 630$

3. $344 \cdot 627 : (9,107 - 8,978)$ Once more, we calculate the difference inside the parentheses: $9,107 - 8,978 = 129$ Now, we divide $344 \cdot 627$ by 129 to get the result: $344 \cdot 627 / 129 = 1,664$

So, the results are:

1. $14,014$
2. $630$
3. $1,664$
