Mixed Numbers To Decimals 10 100 1000 Practice Activities
Class 5 maths worksheets for changing mixed numbers with tenths, hundredths and thousandths into decimals.
Practice that builds confidence
What the skill means
These Class 5 maths practice activities help children convert mixed numbers into decimals when the fractional part has a denominator of 10, 100 or 1000. Learners connect the whole number, numerator and place value to write answers such as 4 7/10 = 4.7, 2 45/100 = 2.45 and 6 125/1000 = 6.125.
The printable worksheets include clear mixed-number questions, place-value based conversions and varied practice from tenths to thousandths. They support the Fractions Decimals chapter by helping children see decimals as another way to write parts of a whole, not as a new or separate idea.
A mixed number has a whole-number part and a fraction part. In this topic, the fraction part is always out of 10, 100 or 1000, so it can be written directly using decimal place value. For example, 8 3/10 becomes 8.3 because 3/10 is 3 tenths. Similarly, 5 9/100 becomes 5.09 because 9 hundredths must be placed in the hundredths column.
How the practice progresses
The worksheets move from easier tenths to hundredths and thousandths, so children build accuracy step by step. They practise reading the denominator, deciding the number of decimal places, and combining it with the whole number. Questions may include fractions like 12/1000 or 6/100, where zeroes are needed in the decimal form: 7 12/1000 = 7.012 and 3 6/100 = 3.06.
A simple parent routine
At home, ask your child to circle the whole number first, then underline the denominator. Say the place value aloud: “out of 100 means hundredths.” Let the child write the decimal part in a place-value chart with tenths, hundredths and thousandths columns before writing the final answer. After each page, choose three answers and ask, “Does the number still have the same whole-number part?” This quick check catches many mistakes.
Classroom uses for teachers
Teachers can use these printables for classwork during the Fractions Decimals unit, revision after teaching decimal place value, or small-group support for children who confuse fractions and decimals. They also work well as maths centre tasks: one group completes tenths, another works on hundredths, and a challenge group handles thousandths. Answers can be discussed using a board place-value chart.
Common errors to watch for
A frequent error is writing 4 5/100 as 4.5 instead of 4.05. Children may ignore the denominator and only look at the numerator. Another error is changing the whole number, such as writing 2 34/100 as 34.2. Encourage children to keep the whole number before the decimal point and place the numerator according to tenths, hundredths or thousandths.

Why iBloom worksheets help
These iBloom worksheets focus only on mixed numbers with denominators 10, 100 and 1000, so practice stays targeted. The repeated structure helps children notice patterns, while the variety prevents memorising one form. A child-friendly strategy is: “Whole number first, decimal point next, fraction digits in the correct place.”
Helpful answers
Frequently asked questions
What mixed numbers are covered in these worksheets?
They focus on mixed numbers whose fractional parts have denominators of 10, 100 or 1000, such as 3 4/10, 5 27/100 and 8 125/1000.
Why does 6/100 become 0.06 and not 0.6?
Because the denominator is 100, the numerator must be placed in the hundredths column. Six hundredths is written as 0.06; 0.6 means six tenths.
How can my child check a mixed number to decimal answer?
Ask them to check that the whole number stayed the same, then count the decimal places: one place for tenths, two for hundredths and three for thousandths.
Are these worksheets suitable after learning decimal place value?
Yes. They are most useful once children understand tenths, hundredths and thousandths, because the conversion depends on placing digits correctly.
Can teachers use these for revision in the Fractions Decimals chapter?
Yes. The pages give focused revision on connecting fractions and decimals, especially for learners who need more practice with denominators 10, 100 and 1000.
Is this Class 5 mixed numbers to decimals worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 5 mixed numbers to decimals worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this Class 5 mixed numbers to decimals worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
