Answer (1)
To answer the student's questions, we need to convert words into numerical figures and perform a rounding operation.
Write in figures nine thousand, two hundred and four.
The number "nine thousand, two hundred and four" can be written in figures as 9,204 .
Write in figures five thousand and seventy-five.
The number "five thousand and seventy-five" can be written in figures as 5,075 .
The TV programme lasted 138 minutes, which is ______ min to the nearest 10 min.
To round 138 to the nearest 10 minutes, we look at the tens digit and the ones digit. The tens digit is 3, and the ones digit is 8. Since the ones digit (8) is 5 or more, we round up.
Therefore, 138 minutes rounds to 140 minutes when rounded to the nearest 10 minutes.
