How to Convert Mixed Numbers to Decimals Step-by-Step
FAQs on Class 5 Maths: Mixed Numbers to Decimals Practice Worksheet
1. How do you convert a mixed number to a decimal for Grade 5?
To convert a mixed number to a decimal in Grade 5, you keep the whole number part and turn the fraction part into a decimal, then combine them.
- Step 1: Keep the whole number as it is. This will be the number to the left of the decimal point.
- Step 2: Convert the fraction part to a decimal by dividing the numerator by the denominator.
- Step 3: Add the whole number and the decimal together.
For example, to convert 3 7/10, you keep the 3, convert 7/10 to 0.7, and add them to get 3.7.
2. What is a mixed number in Maths?
A mixed number is a value in mathematics that consists of a whole number and a proper fraction combined together.
- It represents a quantity that is greater than one.
- The whole number part signifies the complete units.
- The fraction part signifies the remaining portion that is less than a whole.
For example, in the mixed number 5 1/4, '5' is the whole number and '1/4' is the fraction.
3. Why is it important to learn how to convert mixed numbers to decimals?
Learning to convert mixed numbers to decimals is a vital skill as it helps in comparing numbers easily and is widely used in real-life situations.
- Easier Calculations: It is often simpler to perform operations like addition and subtraction with decimals.
- Real-World Context: Decimals are used for money (e.g., ₹10.50), measurements (e.g., 4.5 km), and more.
- Comparing Values: It is easier to tell if 3.5 is bigger than 3.45 than it is to compare 3 1/2 and 3 9/20.
- Foundation for Advanced Maths: This skill is a building block for topics like percentages and data analysis.
4. What is the easiest way to convert a mixed number with a denominator of 10, 100, or 1000?
The easiest way to convert these mixed numbers is by using your knowledge of decimal place value, as these denominators directly relate to decimal places.
- First, write down the whole number.
- Next, look at the fraction. The numerator becomes the digits after the decimal point.
- The number of zeros in the denominator tells you how many decimal places there should be:
- Denominator 10 (1 zero) means one decimal place (tenths). Example: 4/10 = 0.4
- Denominator 100 (2 zeros) means two decimal places (hundredths). Example: 15/100 = 0.15
- Denominator 1000 (3 zeros) means three decimal places (thousandths). Example: 32/1000 = 0.032
So, for 7 15/100, the answer is 7.15.
5. What are common mistakes students make when converting mixed numbers to decimals?
The most common mistakes involve incorrect decimal point placement or forgetting to include the whole number in the final answer.
- Forgetting the Whole Number: For example, converting 5 1/2 to 0.5 instead of the correct 5.5.
- Wrong Decimal Placement: Writing a fraction like 8/100 as 0.8 instead of the correct 0.08.
- Division Errors: Making calculation mistakes when dividing the numerator by the denominator for more complex fractions.
- Ignoring the Fraction: Simply writing down the whole number and not converting the fraction part at all.
