Question

Arrange the following rational number in descending order
-11/20 ; 3/-10 ; 17 /-30 ; -7/15

Answer 1

Step-by-step explanation:

given rational numbers are:-

-11/20;-3/10;-17/30 and -7/15

now change them into numbers having same denominators for comparison.

change them by taking their L.C.M

the L.C.M of 20,10,30,15 is 60.

Then the rationals are -33/60,-18/60,-34/60,-28/60

now arrange them in descending order

-18/60,-28/60,-33/60,-34/60

Answer 2

First we will make their denominator same

they will be as

-33/60;-18/60;-34/60;-28/60

now we will make them in descending order

-18/60;-28/60;-33/60;-34/60

that mean

-3/10;-7/15;-11/20;-17/30
