Question

Use rational numbers -4/5, 7/10 and 11/-20 to verify the associated property of addition of rational numbers
pls answer fast​

Answer 1

Step-by-step explanation:

we know that associative property is

(a+b)+c = a+(b+ c)

l.h.s

(-4/5 + 7/10) +(11/-20)

= (-8+ 7)/10 - 11/20

= -1/10 - 11/20

= -2-11/20= -13/20

r.h.s

-4/5+ ( 7/10 - 11 /20)

= -4/5 +((14-11)/20)

=-4/5+3/20

=( -16+3)/20

= -13/20

l.h.s = r.h.s
