4 2/3 - 2 1/12

here is how i do it 4 - 2 = 2 okie got 2 for the whole number type it down
2 - 1 id really k how to do that the whole taking away thing i nvr understood so if u can explain that in simple terms ty that would help me plus also put some notes down for me to understand better but this is i think its gonna be 7 by taking 3 from the 3 i already have so that turns to nothing theres no more there so then it would be the final answer...

2 7/12 am i correct did i do the math right? leave some notes or me on how the taking away thing works that would probs be very helpful and maybe be a bit helpful for me to do fractions to bc im not good with it and it could help with me going here all the time when i see a fraction. tysm!
