Explanation:

Step1: Align decimals

$$\begin{align*} 46.04\\ -3.29\\ \hline \end{align*}$$

Step2: Subtract from right to left

Borrow 1 from tenths place: $14 - 9 = 5$ (hundredths place).
Borrow 1 from ones place: $9 - 2 = 7$ (tenths place).
Borrow 1 from tens place: $15 - 3 = 12$ (ones place, write 2 carry 1).
Tens place: $3 - 0 = 3$ (carry 1 added: $3+1=4$).
Result: $42.75$

42.75
