Answer 1

Step-by-step explanation:

Question 2 : a ) 18 × (-1) / -29 × (-1)

=》-18/29

b ) 65×(-1) / 91×(-1)

= 》-65/91

c ) -21×(-1)/-49×(-1)

=>21 / 49

=》21÷7/49÷7

=》3/7

d) -36/48 ÷ 2 = -18/24÷2 = 9/12÷3 = 3/4

Question 4:

a) 13/17 b)4/9 c)3/7 d)8/19

Question 5: a) -1/4 & -2/5

LCM=20

=>-1×5/4×5 & -2×4/5×4

=>-5/20 & -8/20

=>-5>-8

THEREFORE 1/-4 > -2/5

b) -5/9 & -5/7

LCM=63

-5×7/9×7 & -5×9/7×9

=-35/63 & -45/63

=-35>-45

THEREFORE-5/9>5/-7

c)-4/9 & 9/4

=-4×4/9×4 & 9×9/4×9

=-16/36 & 81/36

-16/36<81/36

THEREFORE -4/9<9/4

d)-9/12 & -3/4

= -9/12 & -3×3/4×3

= -9/12 & -9/12

=-9/12 = -9/12

THEREFORE -9/12 = 3/-4
