Question

let a ,b, c be the three rational numbers where a=2/3 and c= -5/6 Verify : a+(b+c)=(a+b)+c (Associative property of addition)​

Answer 1

Answer:

19/30

Step-by-step explanation:

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

2/3+(4/5+-5/6)=(2/3+4/5)-5/6

19/30=19/30

where a = 2/3

b = 4/5 (I think you missed it)

c = -5/6
