How to Multiply by a 1-Digit Number

We will learn how to multiply any number by a one-digit number.

Multiplication of a 4-Digit Number by a 1-Digit Number:

1. Multiply 2154 and 4.

Solution:

Step I: Arrange the numbers vertically.

Step II: First multiply the digit at the ones place by 4.

4 × 4 = 16 = 1 ten + 6 ones

Write 6 in the ones column and carry 1 ten to tens place.

Step III: Multiply the digit at the tens place by 4.

5 × 4 = 20 tens

20 + 1 (carried) = 21 tens = 2 hundreds + 1 ten

Write 1 in ten place and carry 2 hundreds to hundreds place.

Step IV: Multiply the digit at hundreds place by 4.

1 hundred × 4 = 4 hundreds

4 hundreds + 2 hundreds (carried) = 6 hundreds

Write 6 in hundreds place.

Step V: Multiply the digit at thousands place by 4.

2 thousands × 4 = 8 thousands

Write 8 in thousands place.

2. Multiply 7325 and 9.

Solution:

Step I: Arrange the numbers vertically.

Step II: First multiply the digit at the ones place by 9.

5 × 9 = 45 = 4 ten + 5 ones

Write 5 in the ones column and carry 4 tens to tens place.

Step III: Multiply the digit at the tens place by 9.

2 × 9 = 18 tens

18 + 4 (carried) = 22 tens = 2 hundreds + 2 ten

Write 2 in ten place and carry 2 hundreds to hundreds place.

Step IV: Multiply the digit at hundreds place by 9.

3 × 9 = 27 hundreds

27 hundreds + 2 hundreds (carried) = 29 hundreds = 2 thousands + 9 hundreds

Write 9 in hundreds place and carry 2 thousands to thousands place.

Step V: Multiply the digit at thousands place by 9.

7 thousands × 9 = 63 thousands

63 thousands + 2 thousands (carried) = 65 thousands = 6 ten thousands + 5 thousands

Write 5 in thousands place and 6 ten thousands in ten thousands place.

3. Multiply 2,634 by 3.

Solution:

Step I: Align the digits.

 Th H T O 2 6 3 4 × 3

Step II: Multiply ones.

4 ones × 3 = 12 ones = 1 ten 2 ones.

Write 2 in ones place and carry 1 to the tens place.

 Th H T O 1 2 6 3 4 × 3

 2

Step III: Multiply tens.

3 tens × 3 = 9 tans.

9 tens + 1 ten (carried) = 10 tens = 1 hundred 0 tens

Write 0 in tens place and carry 1 to the hundreds place.

 Th H T O 1 1 2 6 3 4 × 3

 0 2

Step IV: Multiply hundreds.

6 hundreds × 3 = 18 hundreds.

18 hundreds + 1 thousand (carried) = 19 hundreds = 1 thousand 9 hundreds. Write 9 in hundreds carry 1 to thousands place.

 9 0 2

Step V: Multiply thousands.

2 thousands × 3 = 6 thousands

6 thousands + 1 thousand (carried) = 7 thousands.

Write 7 in thousands place.

 Th H T O 1 1 1 2 6 3 4 × 3

 7 9 0 2

Therefore, the product of 2,634 and 3 = 7,902.

4. Multiply 6492 by 8.
