Write each mixed number as an improper fraction
To write a mixed number as 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:
Step 1: Multiply the whole number by the denominator of the fraction part.
Step 2: Add the result from Step 1 to the numerator of the fraction part.
Step 3: Place the sum from Step 2 over the original denominator of the fraction part.
Step 4: Simplify the resulting fraction if possible.
Let's take an example:
Example: Convert the mixed number 3 1/2 to an improper fraction.
Step 1: Multiply the whole number (3) by the denominator of the fraction part (2): 3 * 2 = 6.
Step 2: Add the result from Step 1 (6) to the numerator of the fraction part (1): 6 + 1 = 7.
Step 3: Place the sum from Step 2 (7) over the original denominator of the fraction part (2): 7/2.
Step 4: The resulting fraction, 7/2, cannot be simplified further since the numerator and denominator do not have any common factors other than 1.
So, the improper fraction equivalent of the mixed number 3 1/2 is 7/2.
