In this Grade 4 worksheet, students extend decimal skills to hundredths with problems like 0.25 + 0.30 = 0.55 and 0.75 - 0.40 = 0.35. The activities emphasize place value, asking learners to align decimal points so hundredths and tenths land in the right columns. Spot-the-error, fill-in, and short-answer tasks help Grade 4 children explain the meaning of digits in tenths and hundredths places clearly.

Decimal Addition and Subtraction
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
0.25 + 0.30 = 0.5
Rewrite: 0.25 + 0.30 = 0.55
2. Fix the sentence:
0.75 - 0.40 = 0.45
Rewrite: 0.75 - 0.40 = 0.35
3. Fix the sentence:
0.42 + 0.15 = 0.67
Rewrite: 0.42 + 0.15 = 0.57
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 0.45 + 0.30 = 0.75
2. 0.85 - 0.20 = 0.65
3. 0.16 + 0.23 = 0.39
4. 0.92 - 0.51 = 0.41
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why does 0.25 equal twenty-five hundredths?
The 2 sits in the tenths place, worth 0.20 or 20 hundredths, and the 5 sits in the hundredths place, worth 5 hundredths. Together they make 25 hundredths, written 0.25 or 25/100.
2. How do place value columns help you subtract 0.75 - 0.40?
Lining up the decimal points puts 7 tenths above 4 tenths and 5 hundredths above 0 hundredths. Subtracting each column gives 3 tenths and 5 hundredths, which is 0.35.
