Answer 2

HEY HERE IS YOUR ANSWERS ☺☺☺☺

a) -7/27+11/18
First we have to find the LCM
LCM = 3×3×3×2=54

-7×2/27×2 + 11×3/18×3
-14/54+33/54
= -14+33/54
=19/54

b) 31/-4 - {-5/8}
= -31/4 + 5/8
LCM = 8
= -31×2/4×2 + 5×1/8×1
= -62/8 + 5/8
= -62+5/8
= -57/8

c) -16/21 × 14/5
= -16×14/21×5
= -224/105
Dividing both numbers by 7 we get
= -32/15

d)7/6×{ -3/28}
= 7×( -3)/6×28
= -21/168
Dividing both numbers by 21 we get,
= -1/8

e)10/3 ÷ -35/12
= 10×(-12)/ 3×35
= -120/105
Dividing both numbers by 15 we get
= -8/7

HOPE IT HELPS ☺☺☺☺☺☺
