Answer:
To rewrite a mixed number as an improper fraction, you need to multiply the whole number by the denominator of the fraction, then add the numerator. The resulting sum is the numerator of the improper fraction, while the denominator remains the same.
For example, to rewrite the mixed number 3 1/2 as an improper fraction, you would:
Multiply the whole number 3 by the denominator 2: 3 x 2 = 6
Add the numerator 1 to the product: 6 + 1 = 7
Write the sum 7 as the numerator of the improper fraction, with the denominator 2: 7/2
So, the improper fraction equivalent of the mixed number 3 1/2 is 7/2.
