Multiplying 3-Digit Number by 1-Digit Number

Here we will learn multiplying 3-digit number by 1-digit number.

In two different types we will learn to multiply a three-digit number by a one-digit number.

Aultiplication of 3-digit Number by 1-digit Number with Regrouping:

1. Multiply 201 by 3

Step I: Arrange the numbers vertically.

Step II: Multiply the digit at the ones place by 3.

1 × 3 = 3 ones

Step III: Now multiply the digit at the tens place by 3.

0 × 3 = 0 tens

Step IV: Now multiply the digit at the hundreds place by 3.

2 × 3 = 6 hundreds

Thus, 201 × 3 = 603

Multiplication of 3-digit Number by 1-digit Number with Regrouping:

1. Multiply 246 by 4

Step I: Arrange the numbers vertically.

Step II: Multiply the digit at the ones place by 4.

6 × 4 = 24 = 2 tens + 4 ones

Write 4 in the ones column and carry over 2 to the tens column

Step III: Now multiply the digit at the tens place by 4.

4 × 4 = 16 tens

Now, 16 + 2 (carry over) = 18 tens = 1 hundred + 8 tens

Step IV: Now multiply the digit at the hundreds place by 4.

2 × 4 = 8 hundreds

Now, 8 + 1 (carry over) = 9 hundred

$Multiplying 3-Digit Number by 1-Digit Number with Regrouping$

Thus, 246 × 4 = 984

2. Multiply 453 by 6.

Step I: Arrange the numbers vertically.

Step II: Multiply the digit at the ones place by 6.

6 × 3 = 18 = 1 tens + 8 ones

Write 8 in the ones column and carry over 1 to the tens column

Step III: Now multiply the digit at the tens place by 6.

6 × 5 = 30 tens

Now, 30 + 1 (carry over) = 31 tens = 3 hundred + 1 tens

Write 1 in the tens column and carry over 3 to the hundred column.

Step IV: Now multiply the digit at the hundreds place by 6.

6 × 4 = 24 hundreds

Now, 24 + 3 (carry over) = 27 hundreds = 2 thousands and 7 hundreds.

Write 7 at the tens place and 2 at the thousands place.

$Multiply 3-digit Number by a 1-digit Number with Regrouping$

Thus, 453 × 6 = 2718
