Divide : (i)`3/5b y4/(25)` (ii) `(-8)/9b y4/3` (iii)`(-16)/(21)b y(-4)/3` (iv) `8/(13)b y3/(-26)`

Text Solution

Verified by Experts

(i)`3/5-:4/25`
Reciprocating the second value and putting the sign of multiplication
We have
`=3/5xx25/4`
`=(3xx5)/4`
`=15/4`
(ii)`8/9-:4/3`
`=8/9xx3/4`
`=2/(3)`
(iii)`-16/21-:-4/3``=16/21xx3/4`
`=4/(7)`
(iv)`8/13-:-3/26`
`=8/13xx(-26/3)`
`(8xx2)/(3)`
=`16/3`
