Question

Verify commutative property of rational numbers when x=-2/5, y=-9/10

Answer 1

hiii. ..........friend

the answer is here,

x=-2/5 & y =-9/10.

=> x+y =y+x

$= > \: \frac{ - 2}{5} + \frac{ - 9}{10} = \frac{ - 9}{10} + \frac{ - 2}{5}$

$= > \: \frac{ - 4 - 9}{10} = \frac{ - 9 - 4}{10}$

$= > \: \frac{ - 13}{10} = \frac{ - 13}{10}$

LHS =RHS.

Hence, The commutative property is verified.

:-)Hope it helps u.
