For the abacus number 432:
The rightmost rod (one’s place) shows the digit 2. The second rightmost rod (tens place)
shows the digit 3. The third rightmost rod (hundreds place) shows the digit 4.Therefore,
the number represented by the abacus is 432.
To find 50 less than this number, we subtract 50 from it:
432 - 50 = 382
So, 50 is less than the number shown on the abacus is 382.
The rightmost rod (one’s place) shows the digit 2. The second rightmost rod (tens place)
shows the digit 3. The third rightmost rod (hundreds place) shows the digit 4.Therefore,
the number represented by the abacus is 432.
To find 50 less than this number, we subtract 50 from it:
432 - 50 = 382
So, 50 is less than the number shown on the abacus is 382.

The rightmost rod (one’s place) shows the digit 1.
The second rightmost rod (tens place) shows the digit 5.
The third rightmost rod (hundreds place) shows the digit 2.
To calculate the double of the number, we multiply 251 by 2:
251 × 2 = 502
So, the double number represented by the abacus (251) is 502.

On an abacus, each rod represents a specific place value, such as ones, tens, hundreds, etc. In this case, we have a three-digit number and the abacus shows the digits 3, 5, and 4.
The rightmost rod (one’s place) shows the digit 4.
The second rightmost rod (tens place) shows the digit 5.
The third rightmost rod (hundreds place) shows the digit 3.
Therefore, the number represented by the abacus is 354.

To find the half value of the number displayed on the abacus (424), we need to divide it by 2.
Dividing 424 by 2 gives us:
424 ÷ 2 = 212
So, the half value of the number displayed on the abacus is 212.

For the abacus number 444:
The rightmost rod (one’s place) shows the digit 4. The second rightmost rod (tens place) shows the digit 4. The third rightmost rod (hundreds place) shows the digit 3. Therefore, the number represented by the abacus is 344.
To find 100 more than this number, we add 100 to it:
344 + 100 = 444
So, 100 is more than the number shown on the abacus is 444.
In this case, if the number shown on the abacus is 344, adding 100 to it gives us the value 444.
