I’ll make it easier, so for number 2 on number 6 7/8 times 8 and 6 and you have 48, then add the top number which would be 55. Then for the second number, 4 1/3 do the same thing! 4*3= 12+1= 13 then add 13+55 and your answer is 68! Then put it in fraction form! 17/25, then all you do is simplify it! If it can’t be simplified (17/25 can not be simplified), it stays the same. Hope that helps! :)
