1. Change both mixed numbers to improper fractions.
45 1/4: 45x4= 180 + 1= 181.......181/4
11 9/10: 11x10= 110 + 9= 119.....119/10
2. To subtract, you need a common denominator. Find lowest common denominator of 4 and 10. LCD is 20. Now change both fractions to have 20 as new denom.
181/4 becomes 905/20 (4x5 is 20, so 181x5= 905)
119/10 becomes 238/20 (10x2 is 20, so 119x2= 238)
905/20 - 238/20 = 667/20
Change answer to a mixed number
667 divided by 20= 33 R 7
Final answer: 33 7/20 (33.35 is a correct answer, but I assume you need your answer as a fraction.)
