To multiply two mixed numbers together, you must first convert them into vulgar fractions. This is done by multiplying the units by the denominator and adding the result to the numerator. In this case 1 1/4 would become 5/4, and 3 2/3 would become 11/3

To multiply these together, you multiply both denominators and numerators. So 5x11 = 55. 4x3 = 12. Thus the result is 55/12

This can be converted back into a mixed number as 4 7/12
