How to approach decimal basics

Decimals extend place value to tenths, hundredths, and beyond. The decimal point separates whole-number places from fractional places.

Reading decimals by place value prevents confusion: 4.37 is four and thirty-seven hundredths, not four point thirty-seven whole units.

Learning objectives

  • Identify decimal place values
  • Write decimals in expanded and word form
  • Compare decimals by aligning place values

Skills to review first

  • Whole-number place value
  • Fractions with denominators 10 and 100
  • Using zero as a placeholder
Worked example

Follow the reasoning step by step

Write 4.37 in expanded form.

  1. The 4 is in the ones place.
  2. The 3 is in the tenths place, so its value is 0.3.
  3. The 7 is in the hundredths place, so its value is 0.07.
  4. Add the place values.

Solution: 4 + 0.3 + 0.07.
