Step-by-step explanation:
the division of 2 fractions is the same as the multiplication with a top/down version of the second fraction.
in short
a/b / c/d = a/b × d/c
and we all remember, that - × - = +
right ?
the same as + × + = +
only mixed multiplications create a negative result :
- × + = + × - = -
all the same applies also to divisions, by the way.
so, the 4th answer option is correct.
3/4 × 12/8
