You cannot multiply mixed numbers, so you have to turn 2 3/4 into a mixed number by doing denominator x whole number x numerator now 2 3/4 turns into 11/4. Now you do 11/4 x 5, or 11/4 x 5/1 ( same thing ). The product of these two fractions is 55/4. Turn it into a mixed number and it turn into 13 3/4.
