Answer 2

Answer:

option [D]

Explanation:

4.32

If replacing 3 by 7 increases a number by 0.4, this must mean that the 3 is in the tenths place.

We need to find the option where 3 is in the tenths place.

4.32 is the only such option.

You can check if this answer is correct by subtracting 4.72 - 4.32. The result should be 0.4.
