Question

verify the commutative property for addition and multiplication for the rational numbers -10/11 & -8/33​

Answer 1

Answer:

9/11 and 2/13

Adding both the numbers,

=9/11+2/13

Taking L.C.M. we get,

=(117+22)/143

We get,

=139/143

And 2/13+9/11

Again taking L.C.M. we get,

=(22+117)/143

We get,

=139/143

Therefore,

9/11+2/13=2/13+9/11.
