Let's solve this subtraction problem step by step, aligning the decimal points.
700.25 - 342.72 -------
First, subtract the hundredths place: 5 - 2 = 3.
700.25 - 342.72 ------- 3
Next, subtract the tenths place: 2 - 7. We need to borrow from the ones place. The 0 becomes 10, and the 2 becomes 12. So, 12 - 7 = 5.
700.25 - 342.72 ------- .53
Now, subtract the ones place. We borrowed 1 from the 0, making it 9. So, 9 - 2 = 7.
700.25 - 342.72 ------- 7.53
Next, subtract the tens place. We borrowed 1 from the 0 (which became 9), so now it's 9. We borrowed 1 from the 7 (making it 6), so the tens place is now 9. So, 9 - 4 = 5.
700.25 - 342.72 ------- 57.53
Finally, subtract the hundreds place. We borrowed 1 from the 7, making it 6. So, 6 - 3 = 3.
700.25 - 342.72 ------- 357.53
Ответ: 357.53
