HELP MY !!!!!!!!!!! PLIZ !!!!

Answer 1

a)3/5+4/5=7/5
b)1/3-1/6=2/6-1/6=1/6
c) -1/6
d)-3,8

Answer 2

a) 3/5 + 4/5 = 7/5
b) 1/3 - 1/6 = 2/6 - 1/6 = 1/6
c) 51/3 - 2 = 17 - 2 = 15
d) -42/10 + 21/5 = -21/5 + 21/5 = 0
e) 5/3 + 5/6 = 10/6 + 5/6 = 15/6
f) -14/36 + 15/36 = 1/36
g) -18/60 + 25/60 - 21/60 = 7/60 - 21/60 = -14/60 = -7/30
h) 6/84 - (15/84 - 1/84) = 6/84 - 14/84 = -8/84 = -2/21
i) -18/84 + 27/28 - 10/84 + 1/84 = 9/84 - 10/84 + 1/84 = -1/84 + 1/84 = 0
j) 8/3 - 1/2 + 5/4 - 2/3 - 9/4 = 32/12 - 6/12 + 15/12 - 8/12 - 27/12 = 26/12 + 15/12 - 8/12 - 27/12 = 41/12 - 8/12 - 27/12 = 33/12 - 27/12 = 6/12 = 1/2
