Question

Arrange the following rational no's -5/3 , 7/-12 and 4/15 in descending order.

Answer 1

Answer:

Step-by-step explanation:

-13 by 20,6 by 15, 7 by 12, -9 by 10, 3 by 5

denominator terms are

20 , 15 , 12 ,10 & 5

We will find LCM of these numbers first

20 = 5×2×2

15= 5×3

12 = 3×2×2

10=5×2

5 = 5

LCM = 5×3×2×2 = 60

lets multiply numerator and denominator to make denominator of each number = 60

ascending order

-9/10 , -13/20 , 6/15 , 7/12 , 3/5

descending order will be

3/15 , 7/12 , 6/15 , - 13/20 , -9/10

Answer 2

Step-by-step explanation:

LCM=540

-5/3,7/12,4/15 =

1. = -5×180/540 ,7×45/540,4×36/540
2. = -900/540, 315/540, 24/540

3 therefore you can simply and write or write this an as descending order
