use properties of real numbers to rewrite the expression (3/5)(5/3)..

dont understand.

1. 3*5/5*3=15/15=1

To rewrite the expression (3/5)(5/3), we can use the commutative property of multiplication, which states that the order of factors in a multiplication does not affect the result. Additionally, we can use the associative property of multiplication which states that the grouping of factors in a multiplication does not affect the result.

(3/5)(5/3) can be rewritten by rearranging the factors using the commutative property:

= (5/3)(3/5)

Now, using the associative property, we can group the factors differently:

= [(5/3) * 3] / 5

Since multiplying a number by its reciprocal results in 1, we have:

= (1) / 5

Finally, any number divided by 1 is equal to the original number, so the expression simplifies to:

= 1/5 or simply 0.2 in decimal form.
