Remember

The product of two decimals has as many decimal places as both factors together.
Next, a hundredths grid shows 0.3 times 0.4 as 12 squares, which is 0.12.
When dividing by a whole number, keep the decimal point in line.
Multiplying both numbers by 10, 100, or 1,000 does not change a quotient.
Estimate first to check where the decimal point belongs.

Common mistakes with this 5th grade multiplying decimals quiz

Students place the point by counting from the left in a product. Instead, count decimal places in the factors.
Students drop a zero from a quotient. Also, check by multiplying the quotient by the divisor. Slow down at that step and check it twice.
Students divide by a decimal without scaling. Instead, multiply both numbers by the same power of ten. Slow down at that step and check it twice.
Students pick an expression that scales only one number. Also, the expression must scale both. Slow down at that step and check it twice.

Tips to get a high score

Estimate before you choose. Also, a rounded product shows where the decimal point belongs. Repeat this habit on every problem for the best results.
Check each division by multiplying. Then, the product must equal the dividend. Repeat this habit on every problem for the best results.
Teachers can use the equal expression question as a quick check on scaling. Repeat this habit on every problem for the best results.

5th grade multiplying decimals quiz: frequently asked questions

How do you tell which expression has the same value as a decimal division?

Look for the one that multiplies both numbers by the same power of ten. Also, for 3.6 divided by 0.04, multiplying both by 100 gives 360 divided by 4. So, the quotient is unchanged.

How do you find the cost of a weight at a price per pound?

Multiply the weight by the price per pound. Also, two and a half pounds at 3 dollars per pound cost 7.50 dollars. So, write the answer with two decimal places for money. A quick check like this takes only a few seconds and prevents most errors.

What does a good score on this quiz mean?

Eight or more out of 10 shows that you can place decimal points and scale divisions. Also, a lower score suggests more practice with estimates. Try the quiz again after a day. A quick check like this takes only a few seconds and prevents most errors.
