  4. Ones: 2 + 1 + 1 = 4. Place the decimal point directly below the others. Answer: 4.25.
  5. Check: read the question again. Does your answer give what was asked, with the right unit? Work backwards to see that it fits. ✓

About this generator

Decimals connect whole numbers, fractions and money. These worksheets start with tenths and hundredths in friendly contexts such as prices and lengths, then move on to longer decimals, multiplication and comparing values. Word problems use shopping receipts, running times and recipes so pupils see why place value matters. The easier level keeps to one or two decimal places, while the harder level mixes place values and requires careful alignment of the decimal point. The answer key is calculated by the website, so it always matches the tasks, and every word problem answer includes the correct unit. No sign-up is needed and no personal data is collected.

Popular uses

  • Place value with tenths and hundredths
  • Money and measurement word problems
  • Warm-ups and homework
  • Revision before a test
