Answer:

on number line the length of the line segment joining - 5 and 2 is ____________ unit

Answer 2

Answer:

a+b= b+a(closure property)

Step-by-step explanation:

2/3 + (-3/5)

LC.M. of 3 and 5 is 15.

2*5/3*5 = 10/15

-3*3/5*3 = -9/15

Now, we will add 10/15+ (-9/15) = 1/15

If we reverse this equation, i.e., (-9/15) + 10/15, we will achieve the same answer, i.e., 1/15.
