Answer:
9/20
Step-by-step explanation:
so since trentons pet eats 4/5 of the food each day and marias eats 1.25 each day so we cant put 4/5 and 1.25 to see wat the awnser is so we make 1.25 a fraction 1 1/4 but the demoninators arent the same so what we do is make them the same so i multiply 4x5 and get 20 that is out new denominator and 4x4 is 16 so the 4/5 is now 16/20 and the 1 1/4 is 1 5/20 then subtract but since we have a whole number we subtract that first but they dont go together but we do it anyway and get 4 left over we put the 4 into the 5/20 and get 9/20 and thers ur awnser
