Which are all the partial products of 1,453 x 4 = 5,812
12; 1,600;4,000
12; 800; 16,000
12;200; 1,600; 4,000
12; 800; 1,600; 4,000
To find the partial products of 1,453 x 4, you need to multiply each digit of 1,453 by 4. Here's how you can do it:
1) Start by multiplying the units digit, which is 3, by 4:
3 x 4 = 12
2) Write down the result, which is 12.
3) Next, multiply the tens digit, which is 5, by 4:
5 x 4 = 20
4) Write down the result, which is 20. However, this is a two-digit number, so you need to carry over the tens place. Write down the 0 under the 2 and carry the 2 to the next step.
5) Now, multiply the hundreds digit, which is 4, by 4:
4 x 4 = 16
6) Add the carried-over 2 from the previous step:
16 + 2 = 18
7) Write down the result, which is 18. However, this is also a two-digit number, so you need to carry over the tens place. Write down the 8 under the 8 and carry the 1 to the next step.
8) Finally, multiply the thousands digit, which is 1, by 4:
1 x 4 = 4
9) Add the carried-over 1 from the previous step:
4 + 1 = 5
10) Write down the result, which is 5.
So the partial products of 1,453 x 4 are: 12 (from step 1), 800 (from steps 3-4), 1,600 (from step 5), and 4,000 (from step 8).
Therefore, the correct answer is: 12; 800; 1,600; 4,000
