Question

If a=3/4, b=-1/2 and c= 1/2
Verity :
a. a+b =b +a
b. a+c=c+a
c. (a+b)+c =a+(b+c)​

Answer 1

Answer:

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

Associative property of rational number under addition is given by following:

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

where, a,b and c are rational numbers.

Answer 2

a.3/4-1/2=-1/2+3/4

answer 1/4=1/4

b.3/4+1/2. =1/2+3/4

answer_. 5/4. =5/4

c. (3/4-1/2)+1/2. =3/4+(-1/2+1/2)

answer_. 1/4+1/2 =3/4+

3/4 =3/4
