To convert a mixed number into an improper fraction, follow these steps:

Step 1: Multiply the whole number part by the denominator of the fraction.
Step 2: Add the result to the numerator of the fraction.
Step 3: Write the sum obtained in step 2 as the new numerator.
Step 4: Use the denominator as it was before.
Step 5: Simplify the resulting fraction if needed.

Let's take an example: Convert the mixed number 3 1/2 into an improper fraction.

Step 1: Multiply the whole number part (3) by the denominator (2): 3 × 2 = 6.
Step 2: Add the result (6) to the numerator (1): 6 + 1 = 7.
Step 3: Write 7 as the new numerator.
Step 4: Keep the denominator (2) unchanged.
Step 5: The improper fraction is 7/2.

So, the mixed number 3 1/2 can be written as the improper fraction 7/2.
