Question

-2/3 & 1/5 solution rational numbers commutative

Answer 1

Answer:

Verify commutative property of addition for the following pairs of rational numbers.

−2/−5 and 1/3.

Step-by-step explanation:

−2/−5 and 1/3

Consider,

−2/−5={−2×(−1)}/{−5×(−1)}

=2/5

Now,

2/5+1/3

Taking L.C.M. we get,

=(6+5)/15

=11/15

And 1/3+2/5

Again taking L.C.M. we get,

=(5+6)/15

=11/15

Therefore,

2/5+1/3=1/3+2/5.
