how can you rename a mixed number to help you subtract

Change it to an improper fraction.

Or -- change it to a decimal.

To rename a mixed number, you need to convert it into an improper fraction.

Here's a step-by-step guide on how to rename a mixed number:

Step 1: Determine the whole number part of the mixed number.

Step 2: Multiply the whole number by the denominator of the fraction part.

Step 3: Add the product from Step 2 to the numerator of the fraction part.

Step 4: Place the sum from Step 3 over the denominator to form an improper fraction.

Step 5: Once you have the improper fraction, you can use it for subtraction.

Here's an example to illustrate the process:

Example: Rename 3 1/2 to an improper fraction.

Step 1: Whole number part = 3

Step 2: 3 * 2 (denominator) = 6

Step 3: 6 + 1 (numerator) = 7

Step 4: Improper fraction = 7/2

Now, you can use this improper fraction to subtract from another number or perform any other arithmetic operation.
