Question

Verify the property of commutativity of multiplication for the following.
(a)-3/11, 11/13 (b) 2, 7/8

Answer 1

Step-by-step explanation:

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.
