How to Change Mixed Numbers into Decimals Easily
FAQs on Convert Mixed Numbers to Decimals – Grade 4 Maths Practice
1. How do you convert mixed numbers into decimals?
To convert a mixed number to a decimal, you combine the whole number with the decimal value of the fraction. The process involves keeping the whole number and converting the fraction part by dividing its top number by its bottom number.
- Step 1: Keep the whole number part as it is. This number will go before the decimal point.
- Step 2: Convert the fraction part by dividing the numerator (top number) by the denominator (bottom number).
- Step 3: Add the resulting decimal to the whole number.
For example, to solve 3 ½, you keep the 3 and divide 1 by 2 to get 0.5. The final answer is 3 + 0.5 = 3.5.
2. What is a mixed number example for Class 4?
A mixed number is a value that includes both a whole number and a proper fraction. In Class 4 Maths, these are introduced as part of the fractions and decimals chapter, showing a value that is more than one whole.
- A simple example is 2 ¼, which means 'two and one-quarter'. Here, 2 is the whole number and ¼ is the fraction.
- Another common example is 5 ½, which is 'five and one-half'.
- When converted, 2 ¼ becomes the decimal 2.25.
3. How do you explain converting mixed numbers to decimals to a child?
To explain this concept to a Grade 4 child, use a simple and relatable approach, like thinking about money. The whole number represents full rupees, and the fraction represents paise.
- Step 1: Explain that the whole number is the main part and stays before the decimal point.
- Step 2: For the fraction part, help them convert it. For common fractions like 1/2 (half) or 1/4 (a quarter), relate them to 0.50 and 0.25 respectively.
- Step 3: Combine them. For example, in 4 ½, the 4 is the whole part. The ½ is 0.5. So, the decimal is 4.5.
4. Can mixed numbers be written as decimals?
Yes, any mixed number can be written as a decimal number. A mixed number has a whole part and a fraction part, which directly corresponds to a decimal number having a whole part (before the decimal point) and a decimal part (after the decimal point).
- The whole number of the mixed number becomes the whole number part of the decimal.
- The fraction is converted to a decimal by division, which becomes the decimal part.
- For instance, the mixed number 7 ¾ is equal to the decimal 7.75.
