Answer 2

Answer:

The new three digit number is tu4

Step-by-step explanation:

1) A two digit number has a tens digit of t and a units digit of u.

This implies that the two digit number is tu.

we just have to place t at tens place and u at units place.

2) The digit 4 is placed immediately to the right of u forming a three digit number.

Now three digit number is formed from two digit number tu by placing the digit 4 to the right of u.

By doing this, t moves to the hundreds place, u to tens place and 4 is now at the units place.

3) So the new three digit number is equal to tu4.
