5/6!
Because....1 1/4 can be converted to 5/4 so then the equation would be 5/4-5/12 but when your subtracting the numbers HAVE to have the same denominator and the LCM of 4 and 12 is 12 so then the equation would be 15/12 (because when you change the denominator you also have to multiply the LCM divided by the number which would be 3 times 5) so anyyywwwaaaayyy the equation would be 15/12-5/12=10/12 which can be simplified to 5/6!!!!!!!!!
And there u have it!
One and one-fourth equals to 5 over 4 5/4 times 3/3 equals to 15/12 subtract 5/12 from 15/12 the answer is 10/12 simplest form is 5/6 hope it helped hit the brainiest button!
