Solve: Subtracting 6.54 from 17 in Vertical Format

To solve this problem, we'll follow these steps:

• Step 1: Align the numbers $17$ and $6.54$ for vertical subtraction.
• Step 2: Perform the subtraction starting with the rightmost digit.
• Step 3: Borrow from the whole part if needed to subtract the decimal part correctly.

Now, let's work through each step:
Step 1: Write the numbers vertically with the decimal point aligned:
$\begin{array}{c} \phantom{0}17.00 \\ -\ 6.54 \\ \hline \end{array}$ Step 2: Start subtracting from the rightmost column, which are the hundredths:
Subtract $4$ from $0$. Since we can't subtract a larger number from a smaller one, we'll need to borrow.
Step 3: Borrow 1 from the tenths place, making $0$ in the tenths as 9, and the hundredths as 10. This borrowing changes $17.00$ to $16.9(10)$.
Subtract $4$ from $10$ which gives $6$ in the hundredths:
$\begin{array}{c} \phantom{\ }9.46 \\ \hline \end{array}$ Finally, verify the operations: Subtract $5$ from $9$ to give $4$ in the tenths:
Subtract $6$ from the left part itself given $16$ now, leaving $10$ in the units:
Step 5: Combine these to get our final result $10.46$.

Therefore, the correct solution to the problem is $10.46$, which matches choice $3$ in the provided options.
