Q-4 Estimate the number 1893 to the nearest tens, hundreds, and thousands. Q-5 Fill in the blanks: a. 1111 + (2222 + 3333) = (____ + 3333) + ____

Let's tackle each part of the question step-by-step.
Q-4: Estimate the number 1893 to the nearest tens, hundreds, and thousands.

Nearest Tens:

To estimate a number to the nearest tens, look at the digit in the ones place.
In 1893, the ones digit is 3.
Since 3 is less than 5, we round down.
So, 1893 rounded to the nearest tens is 1890.


Nearest Hundreds:

To estimate a number to the nearest hundreds, look at the digit in the tens place.
In 1893, the tens digit is 9.
Since 9 is 5 or more, we round up.
So, 1893 rounded to the nearest hundreds is 1900.


Nearest Thousands:

To estimate a number to the nearest thousands, look at the digit in the hundreds place.
In 1893, the hundreds digit is 8.
Since 8 is 5 or more, we round up.
So, 1893 rounded to the nearest thousands is 2000.



Q-5: Fill in the blanks for the expression:
1111 + ( 2222 + 3333 ) = ( ​ + 3333 ) + ​
We need to apply the associative property of addition, which states that ( a + b ) + c = a + ( b + c ) .

Original expression: 1111 + ( 2222 + 3333 )
Rewriting it using associative property: ( 1111 + 2222 ) + 3333

Thus, the completed expression is:
1111 + ( 2222 + 3333 ) = ( 1111 + 2222 ) + 3333
