Regroup through thousands 40 tens=_hundreds

40 tens = 4 hundreds.

Step-by-step explanation:

Consider the provided number 40 tens.

According to the place value chart:

Hundreds     Tens     Ones

  100               10           1

Now, consider the number 40 tens.

Here, tens represents 10.

Thus, 40 tens can be written as:

40×10=400

Now, 400 can be written as:

400=4×100

Where, 100 is same as hundreds.

Thus 40 tens = 4 hundreds.
