8 x 7 + (4/4) = 57
2 8/7 divided by 4/7 is the same as 8/7 times 7/4... The 7s then cancel out and you get 8/4 which is 2

7 times with a remainder of 4 or 7.5 times
8 x 7 + (4/4) = 57
four
7 goes into 28 4 times
2 8/7 divided by 4/7 is the same as 8/7 times 7/4... The 7s then cancel out and you get 8/4 which is 2
8
7/8 x 4/5 = 28/40 or 7/10
8(5+4)+7 = 79
5/8 x 4/7 is 5/14.
7 with 4 remaining 60 - 4 = 56 = 8 x 7
