Question

Rational number in descending order 8/7,-9/8,-3/2,0,2/5​

Answer 1

${\huge {\underline {\red {\mathcal {Answer}}}}}$

To arrange them in descending order,

We will first make their denominators same.

Taking L.C.M of the denominators = 280

= 8/7 × 40/40 = 320/280

= -9/8 × 35/35 = -315/280

= -3/2 × 140/140 = -420/280

= 0/ 1 × 280 / 280 = 0/280

= 2/5 × 56/56= 112/280

Now we can easily arrange them according to their order,

= -420/280, -315/280, 0/280, 112/280, 320/280
