Question

associative property of addition for the following rational number. (b) 4 upon5, -3upon10 ,8upon15.

Solution

association property

If a,b&c are two number

So,for associative property for addition it be hold like that

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

Now,we prove this, by example

where

a=4/5

b= -3/10

c= 18/5

First,take L.H.S

a+(b+c)

keep value of a,b&c

=(4/5)+[(-3/10)+(18/5)]

=(4/5)+[(-3*3+8*2)/30]

=(4/5)+[(-9+16)/30]

=(4/5)+[7/30]

=4/5+7/30

=(4*6+7)/30]

=(24+7)/30]

=31/30

Now,take R.H.S

=(a+b)+c

keep value of a,b&c

=[(4/5)+(-3/10)]+(8/15)

=[(4*2-3)/10]+(8/15)

=[(8-3)/10]+(8/15)

=5/10+8/15

=(5*3+8*2)/30

=(15+16)/30

=31/30

here

.L.H.S=R.H.S

so. we can say that associative property satistied for this example
