Question #0d7d0

Answer 1

`D.`

Explanation:

In each Option, the L.H.S. is `6/8={(3)(2)}/{(4)(2)}=3/4.`

Now, in `A," the R.H.S."=51/68={(17)(3)}/{(17)(4)}=3/4.`

In `B, "the R.H.S.="39/52={(13)(3)}/{(13)(4)}=3/4.`

In `C," the R.H.S.="21/28={(7)(3)}/{(7)(4)}=3/4.`

In `D," the R.H.S.="15/24={(3)(5)}/{(3)(8)}=3/8.`

So, `D` is not a true proportion.
