You're welcome.
To turn a mixed number into an improper fraction, you need to convert the whole number and the fraction part into a single fraction. Here's how you can do it:
1. Take the whole number and multiply it by the denominator of the fraction.
2. Add the numerator of the fraction to the result from step 1.
3. Write the sum you obtained in step 2 as the numerator of the improper fraction.
4. Keep the same denominator as the fraction part.
Let's illustrate this with an example:
Suppose you have the mixed number 3 1/2.
1. Multiply the whole number (3) by the denominator (2): 3 * 2 = 6.
2. Add the numerator of the fraction (1) to the result from step 1: 6 + 1 = 7.
3. Write the sum (7) as the numerator of your improper fraction: 7/2.
4. Keep the same denominator (2) as the fraction part.
Therefore, 3 1/2 can be expressed as the improper fraction 7/2.
