Question

Arrange-5/9, 7/12,-2/3and11/18 in the ascending order of their magnitudes.
Also , find the difference between the largest and the smallest of these rational numbers. Express this difference as a decimal fraction correct to one decimal place​

Answer 1

-5/9, 7/12, -2/3, 11/18

LCM of 9,12,3 and 18 is 108.

-5/9=-5×12/9×12=-60/108

7/12=7×9/12×9=63/108

-2/3=-2×36/3×36=-72/108

11/18=11×6/18×6=66/108

Ascending order: -72/108, -60/108, 63/108, 66/108

=-2/3, -5/9, 7/12, 11/18.

Difference between smallest and largest rational number=11/18-(-2/3)

=11/18+2/3

=lcm of 18 and 3 is 18

11/18= 11×1/18×1=11/18

2/3=2×6/3×6=12/18

11/18+12/18

= 23/18

Answer 2

Answer:

Step-by-step explanation:

-5/9, 7/12, -2/3, 11/18

LCM of 9,12,3 and 18 is 108.

-5/9=-5×12/9×12=-60/108

7/12=7×9/12×9=63/108

-2/3=-2×36/3×36=-72/108

11/18=11×6/18×6=66/108

Ascending order: -72/108, -60/108, 63/108, 66/108

=-2/3, -5/9, 7/12, 11/18.

Difference between smallest and largest rational number=11/18-(-2/3)

=11/18+2/3

=lcm of 18 and 3 is 18

11/18= 11×1/18×1=11/18

2/3=2×6/3×6=12/18

11/18+12/18

= 23/18
