Practice Exercises 1 to 5
1 Basic Practice
Practice Exercise 1
Convert the number to word form:
Standard Form:
5,342
Definition:

Word form: Numbers written out using words instead of digits (0-9).

Method:
  1. Break down the number into groups: thousands, hundreds, tens, ones
  2. Identify each part and convert to words
  3. Write each part using words
  4. Connect with appropriate conjunctions
Standard Form
5,342
Word Form
Five thousand three hundred forty-two
Expanded Form
5,000 + 300 + 40 + 2
Thousands

Step 1: Identify thousands group

5,000 → "five thousand"

Step 2: Identify hundreds group

300 → "three hundred"

Step 3: Identify tens and ones

40 + 2 = 42 → "forty-two"

Step 4: Combine all parts

"five thousand three hundred forty-two"

5,342 = Five thousand three hundred forty-two
Final answer:

5,342 in word form is "Five thousand three hundred forty-two"

Applied rules:

• Hyphenation: Compound numbers 21-99 use hyphens (twenty-one, forty-two)

• Conjunctions: Use "and" only for decimals (not used here)

• Grouping: Thousands, hundreds, tens, and ones

Tip 3: Don't say "zero" for place values that are 0.
Tip 4: For large numbers, separate into thousands and remaining digits.
Common errors: Forgetting hyphens, saying "zero", confusing place values.
Memory aids: "Word" means using actual words instead of digits.
Essential rules to remember:

• Hyphen rule: Use hyphens for compound numbers 21-99

• Zero rule: Skip zero place values in word form

• Reading: Word form is read from left to right

• Place values: Ones (1), Tens (10), Hundreds (100), Thousands (1,000)
