Question

Please help me!!!

Show how you could use the Commutative Property to simplify the evaluation of the expression -7/16-1/4-5/16.

Answer 1

-1 is the answer !!!!!!! You

Answer 2

ensure all fractions have the same denominator

we require -
`(1)/(4)` = -
`(4)/(16)`

thus -
`(7)/(16)` -
`(4)/(16)` -
`(5)/(16)`

take out a common factor
`(1)/(16)`

=
`(1)/(16)` (- 7 - 4 - 5 )

=
`(1)/(16)` × - 16 = - 1
