thousands hundreds tens ones 200× 5

1. 5×2,000 = ____

__ times is __.
thousands hundreds tens ones 2000× 5

Explanation:

Step1: Calculate 5×2

$5\times2 = 10$. Here, 5 times 2 ones is 10 ones.

Step2: Calculate 5×20

$5\times20=100$. Since 20 has 2 tens, 5 times 2 tens is 10 tens which is 100.

Step3: Calculate 5×200

$5\times200 = 1000$. 200 has 2 hundreds, 5 times 2 hundreds is 10 hundreds which is 1000.

Step4: Calculate 5×2000

$5\times2000=10000$. 2000 has 2 thousands, 5 times 2 thousands is 10 thousands which is 10000.

Answer:

1. $5\times2 = 10$; 5 times 2 ones is 10 ones.
2. $5\times20 = 100$; 5 times 2 tens is 100.
3. $5\times200 = 1000$; 5 times 2 hundreds is 1000.
4. $5\times2000 = 10000$; 5 times 2 thousands is 10000.
