Key takeaway: This grade 5 decimal operations quiz holds ten multiple-choice questions that move from hundredths grids to money problems. Only one answer is right per question, and the feedback exposes the usual slip. Students add, subtract, multiply and divide decimals, and they practice moving the decimal point correctly. It takes roughly ten minutes.
Take this ten-question quiz to check your skills with decimal operations, from grids and strips to money problems. Each question has exactly one correct answer. Read the explanation after each answer, especially when you miss one, because it shows the common mistake behind the wrong choices.

Remember:
- Line up decimal points before adding or subtracting.
- Write zeros in empty places, such as 2.8 as 2.80, to keep columns even.
- A product has as many decimal places as both factors together.
- Multiplying the divisor and dividend by the same power of 10 keeps the quotient.
- Estimate first, then use the inverse operation to check.
What do the quiz items ask?
Item 1 reads blue and orange squares as 0.83, and item 2 computes 5.2 plus 0.46 to get 5.66. Item 3 subtracts 3.65 from 8 for 4.35. Items 4 to 6 multiply, with 0.6 times 0.7 equal to 0.42 and 1.5 times 2.4 equal to 3.6. Division closes the set: 0.9 divided by 0.3 is 3, 4.8 divided by 0.6 is 8, and 7.35 divided by 5 is 1.47.
Why do wrong answers sound believable?
Each wrong choice comes from a decimal habit. In item 4, a student may choose 4.2 because 6 times 7 is 42 and the point was forgotten. In item 8, others divide 4.8 by 6 and get 0.8. Item 10 tests change: three notebooks at $4.75 cost $14.25, so Jamal gets $5.75 back from $20.
How can you raise your score on the grade 5 decimal operations quiz?
First, round to whole numbers and guess the size. Second, count decimal places in a product. Third, clear the divisor before you divide. Then compare your exact answer with your guess, and fix any gap of a power of 10.
Which review step helps most after this quiz?
Pick your two weakest items and redo them with a place-value chart. Afterward, make up a new problem for each, using prices from a real receipt. Come back to the quiz in a few days to see the change.
