Answer :

To write the number names, you need to express the numerical values in words.

Let's go through each part step-by-step:

  1. For 456:

    • Break down the number: 400 + 50 + 6.
    • Write in words: 'four hundred fifty-six'.
    • So, 456 is written as 'four hundred fifty-six'.
  2. For 218:

    • Break down the number: 200 + 10 + 8.
    • Write in words: 'two hundred eighteen'.
    • So, 218 is written as 'two hundred eighteen'.

Writing numbers in words is helpful in improving understanding of place values and is often used in official documents and checks to avoid ambiguity.
