Repeated Reasoning Explain how finding 35 ÷ 7 can help you find 350 ÷ 70.
× 3 3 = 15 15 × 3 3 = 150 150 × 3 3 = 1,500 1,500
× 30 30 = 150 150 × 30 30 = 1,500 1,500 × 30 30 = 15,000 15,000

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.
Example Find 1,200 ÷ 40.
Think: 12 ÷ 4 = Division fact
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.
Think: 36 ÷ 1 = Division fact
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.
