## -3 / 4 , 5 / 12 , – 7 / 16 , 9 / – 24

= > – 3 / 4 , 5 / – 12 x ( -1 ) ( -1 ) , -7 , 16 , 9 , 16 x ( -1 ) ( -1 ) .

= > – 3 / 4 , – 5 / – 12 , -7 / 16 , – 9 / 24 .

= > – 3 / 4 = – 3 x 12 , 4 x 12 = – 36 / 48 .

= > – 5 / 12 = – 5 x 4 , 12 x 4 = – 20 / 48 .

= > – 7 / 16 = – 7 x 3 , 16 x 3 = -21 / 48 .

= > – 9 / 24 = – 9 x 2 , 24 x 2 = – 18 / 48 .

### – 3 / 4 < – 7 / 16 < – 5 / 12 < – 9 / 24 .

Step-by-step explanation:

2. Step-by-step explanation:

to do so, we first equalize denominators of all rational numbers....

we should find out the common factor of all rationals...

1) 2/3 × 12/12 = 24/36

4/9 × 4/4 = 16/36

5/12 × 3/3 = 15/36

7/18 × 2/2 = 14/36

so, we can find descending order now easily,

14/36, 15/36, 16/36, 24/36

=7/18, 5/12, 4/9, 2/3

2) 3/4 × 12/12 = 36/48

5/12 × 4/4 = 20/48

7/16 × 3/3 = 21/48

9/24 × 2/2 = 18/48

as usual,

18/48, 20/48, 21/48, 36/48

= 9/24, 5/12, 7/16, 3/4

HOPE THIS HELPS U.......

AND U FELT HAPPY........
