Write the numbers in short form.1. 40,00,000 + 2,00,000 + 60,000 + 2,000 + 800 + 70 + 1 =2. 60,000 + 3,000 + 200 + 8 =3. 70,00,000 + 5,00,000 + 80,000 + 4,000 + 300 + 7 =4. 9 x 10,00,000 + 7 x 1,000 + 8 x 100 + 9 x 10 + 3 =5. 4 x 10,000 + 3,000 + 200 + 70 + 7 =COMPARISON OF NUMBERSCASE - 1 : When two numbers have different number of digits.Example 1 : Which is greater - 4,327 or 52,134 ? Write the numbers in the place value chart. TTh Th H T O4 3 2 75 2 1 3 4Clearly, the number which consists of more number of digits is always greater than the number that consists of less number of digits.Therefore, 52,134 > 4,327.
