Question

To change a mixed number to an improper fraction, multiply the denominator of the fraction by the ____________ and add the _______________ of the fraction. Place this value over the denominator to make the improper fraction.

Answer 1

To convert a mixed number to an improper fraction, multiply the denominator by the whole number part, add the numerator, and place the sum over the original denominator.

Step-by-step explanation:

To change a mixed number to an improper fraction, multiply the denominator of the fraction by the whole number part of the mixed number and add the numerator of the fraction. Place this sum over the original denominator to make the improper fraction.

Let's apply this rule with an example. Imagine you have the mixed number 3 2/5. You would multiply the denominator (5) by the whole number (3) to get 15. Then, you would add the numerator of the fraction (2) to get 17. The improper fraction is then 17/5.

When multiplying fractions, you multiply the numerators together and then multiply the denominators together. In contrast, when converting a mixed number to an improper fraction, you're combining the whole number and the fractional part into a single fraction, increasing the size of the numerator accordingly.
