Answer 1

1.
45 : 5 = 9
557 * 2 = 1114
500 : 5 = 100
2.
было - 455 яблок
украли - 455 : 2
выросло - (455 : 2) * 2
(455 : 2) * 2 = 227,5 * 2 = 455
ответ: осталось столько же, сколько и было, 455

Answer 2

Solving Math Problems for 3rd and 4th Graders

If you're looking for something to do and want to work on some math problems, I'd be happy to help you with that!

1. Division and Multiplication: - To solve the equation 45 ÷ 5, we divide 45 by 5, which equals 9. Then, we multiply 557 by 2, which equals 1114. Finally, we divide 500 by 5, which equals 100.

2. Word Problem with Apples: - In the garden, there were 455 apples. Vanya stole twice as many, which is 910 apples. Then, the number of apples grew twice as much, making it 1820 apples. To find out how many apples were left, we subtract the total stolen and grown apples from the original amount: 1820 - 910 = 910 apples left.

I hope this helps! Let me know if you have any other math problems or questions.
