You can use place value and basic division facts to divide tens,hundreds, or thousands by one-digit numbers or multiples of ten.

Example Find 6,300 ÷ 7.

Think: 63 ÷ 7 = Division fact

6,300 ÷ 7 = hundreds ÷ 7 Use place value.

= hundreds Divide.

=

So, 6,300 ÷ 7 = .

Because multiplication and division are inverse operations, you can use multiplication to

check your answer.



120 ÷ 40 = 12 tens ÷ 4 tens = Use place value.

1,200 ÷ 40 = 120 tens ÷ 4 tens =

So, 1,200 ÷ 40 = .

You can write 1,200 as 12 hundreds or 120 tens. Because the divisor is 40, write 1,200 as 120 tens.

Example A blue whale’s heart beats once every 10 seconds.How many times does the blue whale’s heart beat in 1 hour?

Think: How many seconds are in 1 hour?

There are 60 seconds in 1 minute, and 60 minutes in 1 hour.So, multiply 60 by 60 to find how many seconds are in 1 hour.

60 × 60 = 3,600

Divide 3,600 by 10 to find how many times the blue whale’s heart beats in 1 hour.


360 ÷ 10 = 36 tens ÷ 1 ten = Use place value.

3,600 ÷ 10 = 360 tens ÷ 1 ten =

So, the blue whale’s heart beats times in 1 hour.
