Number Sense & Roman Numbers Class -V

Converting the Roman numerals to Arabic numbers gives: XIV = 14, XLIV = 44, XXII = 22, LIII = 53, and LXII = 62. Since 22 (XXII) is placed after 44 (XLIV), the list is not in correct ascending order, making the statement false.

First, calculate the total number of stamps: 234 + 56 = 290. To write 290 in Roman numerals, we represent 200 as CC and 90 as XC (10 subtracted from 100), resulting in CCXC.

To find the smallest number, we first compare the number of digits. The number 567,345 has only 6 digits, whereas the other numbers have 7 or 8 digits, making 567,345 the smallest.

Comparing the place values from left to right, we look at the ten-millions place (all have 7 except D which has 2) and then the millions place (all have 2). Next, looking at the hundred-thousands place, option B has a 2 (72,200,000) while options A and C have 0. Thus, 72,200,000 is the greatest number.

The place value of any digit is the digit multiplied by its position value. Since any number multiplied by zero is zero, the place value of the digit 0 in any number is always zero.

In the international place value system, the digit 3 is in the ten thousands place. Therefore, its place value is 3 ten thousands, which is equal to 30,000 or 30 thousands.

Eighty crore is represented as 80,00,00,000 and one thousand is 1,000. Adding these together gives 80,00,01,000, which is written as 800001000 without separators.

In the international system, "four hundred fifty eight million" is 458,000,000, "eighty five thousand" is 085,000, and "eight hundred and twenty five" is 825. Combining these parts gives the number 458,085,825.
