Пошаговое объяснение:

1. (215-9)×3-288÷9=586

1) 215-9=206

2) 206×3=618

3) 288÷9=32

4) 618-32=586

2. 345÷5×6+563-239=538

1) 345÷5=69

2) 69×6=414

3) 414+563=977

4) 977-239=538

3. 532÷7×10-450=310

1) 532÷7=76

2) 76×10=760

3) 760-450=310

Answer 3

Sure, I can help you solve these examples. Let's solve them one by one in a column:

1. (215-9)×3-288÷9 First, solve the parentheses: 215 - 9 = 206 Then, multiply by 3: 206 × 3 = 618 Next, divide 288 by 9: 288 ÷ 9 = 32 Finally, subtract: 618 - 32 = 586

2. 345÷5×6+563-239 First, divide 345 by 5: 345 ÷ 5 = 69 Then, multiply by 6: 69 × 6 = 414 Next, add 563: 414 + 563 = 977 Finally, subtract 239: 977 - 239 = 738

3. 532÷7×10-450 First, divide 532 by 7: 532 ÷ 7 = 76 Then, multiply by 10: 76 × 10 = 760 Finally, subtract 450: 760 - 450 = 310

So, the solutions to the given examples are: 1. 586 2. 738 3. 310
