Step-by-step explanation: To get the mixed number Eleven Fourths, you have to multiply 4x2 (4 as the denominator and 2 as the whole number) to get 8, and add 3 (numerator) to get 11, and then put 4 over it as the original denominator to get 11/4. Then, just plug back in the numbers: 11/4 x 8/9 (Eleven-Fourths times Eight-Ninths)
