Step 1: Write the numbers down Write your mixed numbers down on a piece of paper to convert them to improper fractions. Step 2: Convert to improper fraction Multiply the denominator -- the bottom number of the fraction -- by the whole number, and then add the top number of the fraction -- the numerator. Write the product on top of the denominator. Tip For example, the mixed numbers in two and a half times three and two-fifths convert to the improper fractions five halves and seventeen-fifths. Step 3: Write the improper fractions Write the improper fractions side-by-side on your paper. Step 4: Multiply the numerators Multiply the numerators and write the product as the numerator of your solution. Tip The product of five halves times seventeen-fifths will have a numerator of 85.
