They are:
30*20, 30*8, 2*20 and 2*8.
30 x 20 = 600 30 x 8 = 240 4 x 20 = 80 4 x 8 = 32
32 and 160
To find the partial products for 15 x 32, you can break down the numbers: 15 can be expressed as 10 + 5, and 32 as 30 + 2. You then calculate: 10 x 30 = 300 10 x 2 = 20 5 x 30 = 150 5 x 2 = 10 Adding these partial products together: 300 + 20 + 150 + 10 = 480. Thus, the answer for 15 x 32 is 480.
To find the partial product of 4 x 27, you can break down 27 into its components. For example, 27 can be expressed as 20 + 7. Then, you calculate the partial products: 4 x 20 = 80 and 4 x 7 = 28. Adding these together gives you a total of 80 + 28 = 108, so the partial products lead to the final result of 4 x 27 = 108.
(8 x 60) + (8 x 4) 480 + 32 = 512
34 x 28 = 34 x (20 + 8) First partial product is: (30 + 4) x 8 = 240 + 32 Second partial product is: (30 + 4) x 20 = 600 + 80 Sum of partial products = total product = 600 + 240 + 80 + 32 = 952
30 x 20 = 600 30 x 8 = 240 4 x 20 = 80 4 x 8 = 32
32 and 160
To find the partial products of 28 times 14, you would multiply each digit in the ones place of the second number (4) by each digit in the ones place of the first number (8), resulting in 32. Next, you would multiply each digit in the tens place of the second number (1) by each digit in the ones place of the first number (8), resulting in 8. Finally, you would add these two products together to get the final answer of 392.
4 x 20 = 80 4 x 7 = 28 80 + 28 = 108 4 x 27 = 108
how to find the partial products of a number
(8 x 60) + (8 x 4) 480 + 32 = 512
The two partial products of 42 X 28 are 42 X 8 (336) and 42 X 2 (84). To get the actual answer, you shift the partial product (42 X 2) one decimal space to the left and add it to the other partial product, (42 X 8). 42 X 2 = 84. Now, shift 84 one decimal space to the left. This gives you 840. 42 X 8 = 336. Now add 336 to 840 to get the final result, 1176.
20 x 40 = 800 8 x 40 = 320 3 x 20 = 60 3 x 8 = 24
Partial products of 87 times 65 would be 80 x 60 and 80 x 5 and 7 x 60 and 7 x 5. Partial products allow for the multiplication of whole numbers.
The partial products are: 42 * 28 = (40 + 2)*(20 + 8) = 40*20 + 40*8 + 2*20 + 2*8 = 800 + 320 + 40 + 16
700 and 210 are the answers to partial products of 77 times 30
