We will learn how to multiply 3-digit numbers by 2-digit numbers.
Multiplication by 3-Digit Numbers × 2-Digit Numbers:
Step-by-step procedures of multiplying 3-digit numbers by 2-digit numbers.
I. Multiply 148 by 18.
Th H T O 4 1 8 × 1 8 3 3 4 4 1. + 4 1 8 0 2. 7 5 2 4 3. |
1. 18 = 1 ten and 8 ones Multiply 8 ones by all the numbers 418 × 8 ones = 3344 ones 2. Multiply 1 ten by all the numbers 418 × 1 ten = 418 tens = 4180 3. Add the two products [1. + 2.] 3344 + 4180 = 7524 |
Thus, 148 × 18 = 7524
II. Multiply 354 by 24.
Th H T O 3 5 4 × 2 4 1 4 1 6 1. + 7 0 8 0 2. 8 4 9 6 3. |
1. 24 = 2 tens and 4 ones Multiply 4 ones by all the numbers 354 × 4 ones = 1416 ones 2. Multiply 2 tens by all the numbers 354 × 2 tens = 708 tens = 7080 3. Add the two products [1. + 2.] 1416 + 7080 = 8496 |
Thus, 354 × 24 = 8496
Multiplying 3-Digit by 2-digit Numbers:
III. Multiply 163 by 25.
Solution:
Step 1. Arrange the numerals as shown
Step 2. Multiply 163 by 5 ones
163 × 5 = 815 ones
Step 3. Multiply 163 by 2 tens
163 × 2 tens = 326 tens
= 3260
Step 4. Add both the products
815 + 3260 = 4075
Thus, 163 × 25 = 4075
