Ms. Swanson asked the question, "How does knowing the fact 6×5 help you find 60×500?" Maria answered, "I know 6×5 is 30. Now all I have to do is count the zeros and I get 3,000." Use place value understanding to explain why her answer is incorrect.

See explanation

Step-by-step explanation:

Maria is incorrect as she didn't count the number of zeros properly. After knowing that 6 × 5 = 30, the question is 60×500 which means there are 3 zeros that should be added to the 30 that she got, this will have given her a value of 30,000 which is correct.

She write 3000 which is 3 under thousands rather than 30,000 which is 3 under tens of thousands.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
