Question

Arrange the following rational numbers in descending order : −3/-5,17/30,-8/15,7/-10​

Answer 1

Answer:

Descending order : 3/5 > 17/30 > -8/15 > -7/10

Step-by-step explanation:

The LCM of 5, 30, 15 and 10 is 30  

Multiplying the numerators and denominators to get the denominator equal to the LCM i.e. 30  

Consider (3/5) Multiply both numerator and denominator by 6, then we get  

(3/5) × (6/6) = (18/30)  

Consider (8/-15) Multiply both numerator and denominator by 2, then we get  

(8/-15) × (2/2) = (16/-30)  

Consider (-7/10) Multiply both numerator and denominator by 3, then we get  

(-7/10) × (3/3) = (-21/30)  

In the above equation, denominators are same Now on comparing the ascending order is: (-7/10) < (8/-15) < (-17/30) < (3/5)
