Find the product. × H T O 3 2 4

We need to multiply 32 and 4 . Arrange the numbers column wise. Multiply the ones, 2 ones × 4 = 8 ones H T O 3 2 × 4 8 Write 8 under the ones column. Multiply the tens, 3 tens × 4 = 12 tens × H T O 3 2 4 1 2 8 Write 2 under the tens column and 1 in hundreds column. Therefore, the product is 128 .

Find the product. × H T O 4 9 3

We need to multiply 49 and 3 . Arrange the numbers column wise. Multiply the ones, 9 ones × 3 = 27 ones H T O 2 4 9 × 3 7 Write 7 under the ones column and carry 2 under the tens column. Multiply the tens, 4 tens × 3 = 12 tens 12 tens + 2 tens (carried over) = 14 tens H T O 2 4 9 × 3 1 4 7 Write 4 under the tens column and 1 under the hundreds column. Therefore, the product is 147 .

Find the product. T O 2 8 × 3

We need to multiply 28 and 3 . Arrange the numbers column wise. Multiply the ones, 8 ones × 3 = 24 ones T O 2 2 8 × 3 4 Write 4 under the ones column and carry 2 to tens place. Multiply the tens, 2 tens × 3 = 6 tens 6 tens + 2 tens (carried over) = 8 tens T O 2 2 8 × 3 8 4 Write 8 under the tens column. Therefore, the product is 84 .

Find the product. × H T O 7 3 7

We need to multiply 73 and 7 . Arrange the numbers column wise. Multiply the ones, 3 ones × 7 = 21 ones H T O 2 7 3 × 7 1 Write 1 under the ones column and write carry 2 under tens place. Multiply the tens, 7 tens × 7 = 49 tens 49 tens + 2 tens (carried over) = 51 tens H T O 2 7 3 × 7 5 1 1 Write 1 under the tens column and 5 under hundreds column. Therefore, the product is 511 .

Multiply by using the Lattice method, 19 × 5 .

We need to find the product of 19 and 5 by using Lattice method. 19 is a 2 -digit number and 5 is a 1 -digit number. Make a grid of 2 columns and 1 row and draw diagonals across each box in the grid. Write the numbers to be multiplied as shown below. Multiply 1 and 9 by 5 and write the products as shown. Add up the diagonal numbers to get the result. Therefore, the product is 95 .

Multiply by using the Lattice method, 23 × 7 .

We need to find the product of 23 and 7 by using Lattice method. 23 is a 2 -digit number and 7 is a 1 -digit number. Make a grid of 2 columns and 1 row and draw diagonals across each box in the grid. Write the numbers to be multiplied as shown below. Multiply 2 and 3 by 7 . We know that, 7 × 2 = 14 and 7 × 3 = 21 Write the products as shown. Add up the diagonal numbers to get the result. Therefore, the product is 161 .

Multiply by using the Lattice method, 35 × 3 .

We need to find the product of 35 and 3 by using Lattice method. 35 is a 2 -digit number and 3 is a 1 -digit number. Make a grid of 2 columns and 1 row and draw diagonals across each box in the grid. Write the numbers to be multiplied as shown below. Multiply 3 and 5 by 3 . 3 × 5 = 15 3 × 3 = 9 Write the products as shown. Add up the diagonal numbers to get the result. Therefore, the product is 105 .

Multiply by using the Lattice method, 46 × 7 .

We need to find the product of 46 and 7 by using Lattice method. 46 is a 2 -digit number and 7 is a 1 -digit number. Make a grid of 2 columns and 1 row and draw diagonals across each box in the grid. Write the numbers to be multiplied as shown below. Multiply 4 and 6 by 7 . We know that, 7 × 4 = 28 and 7 × 6 = 42 Write the products as shown. Add up the diagonal numbers to get the result. Therefore, the product is 322 .
