Regrouping of Numbers from Ones to Tens:

Writing a quantity in several methods known as regrouping.

Allow us to contemplate the quantity 18. We are able to consider it in these two methods:

18 ones could be regrouped as 1 ten 8 ones.

Now, contemplate the quantity 24.

Once more, 2 tens 15 ones is identical as 3 tens 5 ones.

Extra Examples:

18 ones = 1 ten + 8 ones

14 ones = 1 ten + 4 ones

3 tens + 12 ones = 4 tens + 2 ones

5 tens + 19 ones = 6 tens + 9 ones

1 ten +18 ones = 2 tens + 8 ones

Regrouping of Numbers from Tens to Ones:

Allow us to contemplate the quantity 16. We are able to consider it in two methods.

1 ten 6 ones could be regrouped as 16 ones.

Now, contemplate the quantity 23.

2 tens 3 ones could be regrouped as 1 ten 13 ones.

Once more, 3 tens 2 ones is identical as 2 tens 12 ones
