Question

lat a,b,c be the 3. rational numbers where a =3/2,b=4/5and c=-5/6 verify:
a) a+(b+c)=(a+b)+c.
b)a×(b×c)-(a×b)×c
pls answer both the parts its very urgent​

Answer 1

Answer: I hope it'll help you mark me as brainliest.

If a, b, c are rational numbers, then associativity of rational numbers under addition is given by

Step-by-step explanation:

a+b=b+a

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

Answer 2

Answer:

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

3/2 + (⅘+(-⅚)) = (3/2 + ⅘)+(-⅚)

3/2+⅘-⅚ = 3/2+⅘-⅚

45/30 + 24/30 - 25/30 = 45/30 + 24/30 - 25/30

69/30-25/30 = 69/30-25/30

44/30 = 44/30

=>22/15 =22/15
