This is frustrating me.
The formula for division of fractions in my Pre-Calculus book is a/b = a x 1/b.
However, when you apply this to an actual problem, it doesn't make sense. For example:
3/4 divided by (sorry, I don't see a divisor sign in the list of symbols we can choose from) 6/11
This becomes 3/4 x 11/6. So you just flip the 6/11 and use its reciprocal to multiply by. I remember this from high school. However, when thinking about the formula (above), shouldn't it be:
3/4 x 1/11/6 (1 in the numerator and 11/6 in the denominator)? THAT would fit the formula and not merely the reciprocal. "b" is a fraction (6/11). The formula says to place b under a 1 and that's what I did. So I'm confused now. Anyone understand what I'm missing? Thanks.
