Question

verify that a+b=b+a for each the following
a) a= 4/5 ; b= -3/10​

Answer 1

Answer:

4/5+(-3/10)=a+b

=0.5

(-3/10)+(4/5)=b+a

=0.5

a+b=b+a

hence verified

Answer 2

Step-by-step explanation:

a+b=b+a

a=4/5

b= -3/10

4/5+ (-3/10)= -3/10 +4/5

4/5x2=8/10. (to make denominator same)

8/10+(-3/10)=-3/10+4/5

5/10=5/10

1/2=1/2

0.5=0.5

so , a+b=b+a

hence proved
