Dividing 642: Understanding Place Value

The video tutorial explains how to divide the number 642 by 3. It starts by breaking down 642 into hundreds, tens, and ones. The teacher demonstrates how to evenly distribute the hundreds into three groups, ensuring each group has the same number of hundreds. Next, the tens are divided, and any remainder is converted into ones for further division. Finally, the ones are evenly distributed, resulting in each group having 200s, 110, and 4 ones. The solution shows that 642 divided by 3 equals 214.

What is the initial problem discussed in the video?

• Subtracting 3 from 642

• Dividing 642 by 3

• Adding 642 and 3

• Multiplying 642 by 3

How is the number 642 initially broken down for division?

• Into tens and ones only

• Into hundreds, tens, and ones

• Into thousands, hundreds, and tens

• Into hundreds and thousands

What is the purpose of breaking down the number 642?

• To make it easier to multiply

• To make it easier to divide

• To make it easier to subtract

• To make it easier to add

How many hundreds are there in the number 642?

• 6

• 4

• 3

• 2

What is the first step in dividing the hundreds?

• Place all hundreds in one group

• Divide the hundreds equally among three groups

• Ignore the hundreds

• Convert hundreds into tens

What happens to the tens when they cannot be evenly divided?

• They are converted into ones

• They are discarded

• They are converted into hundreds

• They are left as is

How many tens are initially present in 642?

• 6

• 4

• 2

• 3

What is done with the remaining ten that cannot be evenly divided?

• It is converted into 10 ones

• It is ignored

• It is left in one group

• It is added to the hundreds

Why can't the remaining ten be placed in one group?

• It would increase the total

• It would make the division even

• It would decrease the total

• It would make the division uneven

How many ones are there after converting the remaining ten?

• 12

• 8

• 14

• 10
