Question

arrange the following in descending order. -7/10,8/-15,19/30,-2/-5 by taking with lcm​

Answer 1

Step-by-step explanation:

LCM is 30

-7×3/10×3 = -21/30

-8×2/15×2 = -16/30 ( first multiply and divide this term by -1 and then make the denominator common. This makes it easy)

19×1/30×1 = 19/30

-2/-5 = 2/5 = 2×6/5×6 =12/30

So the descending order:

19/30, 12/30, -16/30, -21/30

= 19/30, -2/-5, 8/-15, -7/10

Hope this helps you...
