Subtracting a Mixed Number from a Fraction

To subtract a mixed number from a fraction, you can convert the mixed number to an improper fraction and then perform the subtraction. Here's a step-by-step guide on how to do this:

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 then add the numerator. The result becomes the new numerator, while the denominator remains the same.

2. Perform the Subtraction: - Once both numbers are in the form of fractions, you can subtract them by subtracting the numerators while keeping the denominator the same.

Let's illustrate this process with an example:

Given: - Mixed number: 2 1/3 - Fraction: 3/5

Example Calculation:

1. Convert the mixed number to an improper fraction: - \(2 \frac{1}{3} = \frac{(2 \times 3) + 1}{3} = \frac{7}{3}\) 2. Perform the subtraction: - \(\frac{7}{3} - \frac{3}{5}\)

Now, you can proceed with the subtraction of the fractions.

This process allows you to subtract a mixed number from a fraction effectively.
