Question

write the following rational numbers in descending order -5/4 , 3/2 , 7/5​

Answer 1

Answer:

-5/4 , 3/2 , 7/5

LCM of 4 , 2 and 5 is 20.

so, for making denominator equals as 20 just multiply required numbers in both numirator and denominator.

=> (-5/4)×(5/5) , (3/2)×(10/10) , (7/5)×(4/4)

=> (-25/20) , (30/20) , (28/20)

Here, we can identify easily which is greater.

and hence, arranged in descending order

(30/20)>(28/20)>(-25/20).

putting original values, (3/2)>(7/5)>(-5/4).
