Write 3 in the ones column.

$1a$

Explanation:

In this step, multiply the digit in the ones place by 3. For instance, if the digit is 0, multiply it by 3, resulting in 0. Write down 0 in the ones column.

Step: 2

Next, multiply the digit in the tens place by 5, i.e., 5 × 3 = 15
Write down 5 in the tens column and carry over 1 to the hundreds column.

$2a$

Explanation:

In this step, 5 is multiplied by 3, resulting in 15. Write 5 in the tens column and carry 1 to the hundreds column.

Step: 3

Now multiply the digit in the hundreds’ place by 3, i.e., 1 × 3 = 3
Add carry 1 to 3, we get 4. Write 4 in the hundreds’ place.

Thus, the product of 150 and 3 is 450.

$3a$

Explanation:

In this step, multiply 3 by the hundreds digit, which is 1: 1 x 3 = 3. Then, add 1 to 3 to get 4. Write 4 in the hundreds place, so 150 x 3 = 450.
