To multiply a multi-digit number by a one-digit number, multiply each digit in the multi-digit number by the one-digit number.
Step 1: Write the second number under the first number so that the corresponding places are lined up.
Step 2: Multiply the bottom number by the ones digit in the top number (9 × 8 = 72). Since 72 has two digits, both digits won't fit in the ones place. So, write the 2 in the ones place of the product, and carry the 7 to the tens column.
Step 3: Multiply the bottom number by the tens digit in the top number (9 × 8 = 72). Then, add the 7 that was carried to the tens column in the previous step (72 + 7 = 79).
