Subtracting a Natural Number from a Mixed Number: Rule

When subtracting a natural number from a mixed number, the process involves converting the mixed number to an improper fraction and then performing the subtraction. Here's the detailed rule for subtracting a natural number from a mixed number:

1. Convert the Mixed Number to an Improper Fraction: - To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. The result becomes the new numerator, and the denominator remains the same. - For example, to convert the mixed number 3 2/3 to an improper fraction: - \(3 \frac{2}{3} = \frac{(3 \times 3) + 2}{3} = \frac{11}{3}\).

2. Perform the Subtraction: - Once the mixed number is converted to an improper fraction, subtract the natural number from the improper fraction. - For example, to subtract 7 from the improper fraction \(\frac{11}{3}\): - \(\frac{11}{3} - 7 = \frac{11}{3} - \frac{21}{3} = -\frac{10}{3}\).

3. Simplify the Result: - If necessary, simplify the resulting fraction.

In summary, the process involves converting the mixed number to an improper fraction, subtracting the natural number, and then simplifying the result.
