How to Subtract Mixed Numbers with Unlike Denominators (Step-by-Step Guide)
FAQs on Subtracting Mixed Numbers with Different Denominators – Class 6 Worksheet
1. How do you subtract mixed numbers with different denominators?
To subtract mixed numbers with different denominators, you must first find a common denominator, then subtract the fractions and whole numbers, borrowing if necessary. The process involves several key steps:
- First, find the Least Common Denominator (LCD) of the fractions.
- Next, convert the fraction parts to equivalent fractions using the LCD.
- Subtract the fractions. If the first fraction is smaller than the second, you will need to borrow from the whole number.
- Finally, subtract the whole numbers and simplify the resulting fraction.
2. What is the easiest way to subtract mixed numbers for Grade 6 kids?
The easiest and most reliable way for a Grade 6 student to subtract mixed numbers is often by converting them into improper fractions first. This method avoids the potentially confusing step of borrowing.
- Convert both mixed numbers into improper fractions.
- Find the Least Common Multiple (LCM) of the different denominators.
- Rewrite both fractions as equivalent fractions with the common denominator.
- Subtract the numerators and keep the common denominator.
- Convert the final improper fraction back into a mixed number.
3. How do you handle borrowing when subtracting mixed numbers?
Borrowing in mixed number subtraction involves taking '1' from the whole number and adding it to the fraction part to make subtraction possible. This is necessary when the first fraction is smaller than the second.
- For example, in 5 1/4 – 2 3/4, you cannot subtract 3/4 from 1/4.
- You borrow 1 from the whole number 5, which leaves you with 4.
- The borrowed 1 is converted to a fraction with the same denominator (in this case, 4/4).
- Add this to the existing fraction: 1/4 + 4/4 = 5/4.
- The problem becomes 4 5/4 – 2 3/4, which can now be solved easily.
4. Can you subtract mixed numbers without converting to improper fractions?
Yes, you can subtract mixed numbers without converting to improper fractions, but this method requires careful handling of the borrowing step. You subtract the whole numbers and fractions separately.
- First, find a common denominator for the fraction parts.
- If the first fraction is smaller than the second, you must borrow 1 from its whole number part.
- Subtract the fractions.
- Subtract the whole numbers.
- While this method works, many students find converting to improper fractions a more straightforward approach.
5. What is the first step in subtracting fractions with unlike denominators?
The most crucial first step in subtracting fractions with unlike denominators is to find a common denominator, specifically the Least Common Denominator (LCD). You cannot perform subtraction until the denominators are the same.
- The LCD is the Least Common Multiple (LCM) of the given denominators.
- Once you find the LCD, you must convert each fraction into an equivalent fraction with this new denominator.
- After this step, you can proceed to subtract the numerators.
