Answer:11/12
Explanation:
3 1/4=13/4. Change to improper
2 1/3=7/3^^^
13/4-7/3=? new equation
4*3=12, find the common denominator(if you're lazy just multiply the denominators with each other) but now you have to do the same with the numerator
13*3(because we multiplied 4 BY 3 in the first equation)
7*4(again because for this one we multiplied 3 BY 4)
39/12-28/12=11/12
