You figure out the amount of chocolate doughnuts sold by multiplying 2/3 by 7 1/4
first you change 7 1/4 to an improper fraction: 7 1/4= 29/4 now multiply 2/3×29/4 by multiplying the two numerators then putting that over the two denominators multiplied: (2×29)/(3×4)=58/12 now simplify:58/12=4 10/12= 4 5/6
the answer is Stanley's doughnut shop sold 4 5/6 trays of chocolate doughnuts
