Here, the given number,

7.05,

Digits of the number are, 7, 0 and 5

The possible numbers are 750, 5.07, 570, ...etc

Hence, after moving the digits of a number we can get an another number,

That is, we can get different number using the same digits.

Therefore, Tanya is correct.

• 5.70;
• 0.57;
• 0.75.

He can even write numbers, where decimal point is in another position. For example, 70.5, 50.7,... and so on or without decimal point: 705, 750 ...

There are a lot of possiblle ways to write different number using the same digits.

Answer: Yes, he is correct.
