Explain how to determine whether or not 11/12 is the correct answer to the problem 1 1/4 - 1 / 3

Answer 1

11/12 is correct

Step-by-step explanation:

To find the result of 1 1/4 - 1/3, we need to write the first number as a fraction, so:

`1(1)/(4)=((1*4)+1)/(4)=(4+1)/(4)=(5)/(4)`

Then, 1 1/4 - 1/3 is equivalent to 5/4 - 1/3, so the correct answer is:

`(5)/(4)-(1)/(3)=(5(3)-4(1))/(4(3))=(15-4)/(12)=(11)/(12)`

Therefore, 11/12 is the correct answer to the problem
