Identify the property shown.
(-5.2 + (-8.4)) + (-2.8) = -(5.2 + 8.4) + (2.8)
a. associative property
b. commutative property
c. opposite of a sum property.

answer is:

1.75 pounds

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
