This easy-level worksheet has students fix sentence errors, fill in blanks, and write short answers to practice decimal operations: add, subtract, multiply, divide skills.
It includes 9 questions across 3 sections for focused practice.

Decimal Operations: Add, Subtract, Multiply, Divide
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
8.4 ÷ 3 = 2.1 because 84 ÷ 3 = 21 and the decimal goes after the first digit.
Rewrite: 8.4 ÷ 3 = 2.8 because 84 ÷ 3 = 28 and the decimal point stays directly above its position in the dividend.
2. Fix the sentence:
6.5 ÷ 5 = 1.5 because 5 goes into 65 thirteen times.
Rewrite: 6.5 ÷ 5 = 1.3 because 5 goes into 65 thirteen times, giving 1.3.
3. Fix the sentence:
9.24 ÷ 4 = 2.36 because 924 ÷ 4 = 236.
Rewrite: 9.24 ÷ 4 = 2.31 because 924 ÷ 4 = 231, so the quotient is 2.31.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. 7.2 ÷ 6 = 1.2
2. 14.4 ÷ 8 = 1.8
3. When dividing a decimal by a whole number, the decimal point in the quotient goes directly above the decimal point in the dividend.
4. 25.5 ÷ 5 = 5.1
Part C: Short Answer
Answer each question in one or two complete sentences.
1. A pack of 4 erasers costs $3.48. How much does one eraser cost? Show your reasoning.
Divide $3.48 by 4: 348 ÷ 4 = 87, so one eraser costs $0.87.
2. Why is it helpful to think of 6.5 ÷ 5 as 65 tenths ÷ 5 when dividing?
Thinking in tenths turns the decimal into a whole-number division (65 ÷ 5 = 13 tenths = 1.3), which is easier to compute.
