Answer 1

A) 2 2/3+ 4 3/4= 8/3+ 19/4= 32/12+ 57/12= 89/12= 7 5/12
b) 1 1/8+ 2 10/11= 9/8+ 32/10= 45/10+ 128/40= 173/40= 4 13/40
c) 4 3/4- 1 1/6= 19/4- 7/6= 57/12- 14/12= 43/12= 3 7/12
d) 3 2/3- 1 1/5= 11/3= 6/5= 55/15- 18/15= 37/15= 2 7/15
e) 3 1/4- 2 5/8= 13/4- 21/8= 26/8- 21/8= 5/8
f) 4 1/6- 2 3/8= 25/6-19/8= 100/24- 57/24= 43/24= 1 19/24
g) 3 1/2- (4 3/4- 2 1/8)= 7/2- (19/4- 17/8)= 7/2- ( 38/9- 17/8)= 7/2- 21/8= 28/8- 21/8= 7/8
h) 2 5/6 - (1 1/8 +2/3)= 17/6- (9/8+ 2/3)= 17/6-( 27/24+ 16/24)= 17/6- 43/24= 68/24- 43/24= 25/24= 1 1/24

Answer 2

A) 2 i 2/3 + 4 i 3/4 = 2 3/12 + 4 9/12 = 6 12/12 = 7
b) 1 i 1/8 + 2 i 10/11 = 1 11/88 + 2 80/88 =3 91/88 = 4 3/88
c) 4 i 3/4 - 1 i 1/6 = 4 9/12 + 1 2/12 = 5 11/12
d) 3 i 2/3 - 1 i 1/5 = 3 10/15 + 1 3/15=4 13/15
e) 3 i 1/4 - 2 i 5/8 = 3 8/32 + 2 20/32 = 5 28/32 = 5 7/8
f) 4 i 1/6 - 2 i 3/8 = 4 4/24 + 9/24 = 13 13/24
g) 3 i 1/2 - ( 4 i 3/4 - 2 i 1/8) = 3 16/32 - ( 4 24/32 - 2 4/32 ) = 3 16/32- 2 20/32 = 28/32 = 7/8
h) 2 i 5/6 - (1 i 1/8 + 2/3) = 2 20/24 - ( 1 3/24 + 8/ 24) = 2 20/24 - 1 11/2 = 1 9/24 = 1 3/8
