This video teaches the viewer how to multiply fractions with mixed numbers. You would first need to multiply the denominator by the whole number, and then add the product to the numerator. This number is your new numerator and the new denominator is the same as before. For example, 2 1/5 = 11/5. Now you have an equation with fractions and no whole numbers. You may now proceed to multiply straight across. Multiply the numerators together to create a new numerator and do the same for the denominators. Your product needs to be converted to a fraction with whole numbers. To do this, you divide the denominator by the numerator. Your remainder in the long division is your new numerator. The quotient is your new whole number. Of course, the denominator stays the same.
