Arrange these rational numbers in descending order 7/10 , 2/5,-11/15,1/6,17/30​

Answer»

Step-by-step explanation:

by FINDING lcm of all DENOMINATOR you will get the answer

their lcm is 30

7/10 will be 21/30

2/5 will be 12/30

-11/5 Will be -22/30

1/6 will be 5/30

17/30 will remain the same as it's denominator is already 30

now just arrange it descending order(BIGGER to SMALLER)

21/30,17/30,12/30,5/30,-22/30

which means your answer is

7/10,17/30,2/5,1/6,-11/15

thank you
