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.
