Which fraction equals to -9/16? A. -3/4 B. 9/-16 C. 9/16 D. 3/4
@phi
any ideas?
I thought about the first one. But I am not too sure.
negative divided by positive is negative. the answer has to be a negative
It's going to be negative, for one
that leaves out C and D
So if it is negative, then the sign cannot be in the denominator. It has to be in the numerator.
No, -(1/2) = (-1/2) = (1/-2)
the sign can be either place (but not both) notice -1/2 is - 1/2 and 1/-2 is - 1/2 all three ways mean the same number
That was what my teacher had said.
It doesn't matter so long as at least one number is negative
So is it B?
ask your teach what is 9 divided by -16 ?
If you want to show a negative fraction, then yes, it's common practice to put the negative number on the top or to the side, but you don't have to
or test with a calculator type in -9/16 and compare that answer to 9 divided by -16 you will get the same number
Wait.... So this is basically seeing what quotients match right?
9 can be factored into 3*3 16 into 2*2*2*2 they have no common prime factors, so 9/16 cannot be simplified. so yes , for this problem top and bottom have to be 9 and 16 and the sign can be put in 3 different places: \[ \frac{-9}{16}, \frac{9}{-16} , - \frac{9}{16} \]
OKay thanks :) Gotta go bye
of course, they could have done this - 18/32 (which simplifies to -9/16) to trick you
