Step-by-Step Solution

To solve this vertical addition problem, we follow these steps:

Step 1: Write the numbers one below the other, aligning columns by place value.
Step 2: Begin with the ones column. Add $7$ (from $47$ ) to $5$ (from $25$ ).
Step 3: Calculate the sum in the ones column: $7 + 5 = 12$ .
Step 4: Since $12$ is greater than $9$ , we write $2$ in the ones place and carry over $1$ to the tens column.
Step 5: Add the tens column: $4$ from $47$ , $2$ from $25$ , and the carried over $1$ .
Step 6: Calculate the tens sum: $4 + 2 + 1 = 7$ .

Therefore, the final sum is $72$ .

By checking the provided choices, the correct choice is: $72$ .
