Question

arrange the following rational number in descendingorder minus 3 by 10, 7 by minus 15, - 11 by 20 ,17 by minus 30​

Answer 1

Answer:

-3/10 < 7/(-15) < -11/20 < 17/(-30)

Step-by-step explanation:

Taking the LCM of 10, 15, 20 & 30 = 60 as denominator,

-3/10 = -18/60

7/(-15) = -7/15 = -28/60

-11/20 = -33/60

17/(-30) = -17/30 = -34/60

-18/60 < -28/60 < -33/60 < -34/60

=> -3/10 < 7/(-15) < -11/20 < 17/(-30)
