The same as any two fractions. In this case, the answer will be negative.
Convert them to improper fractions and proceed. The answer will be positive.
Yes, the product of an odd number of negative fractions is always negative. This is because multiplying two negative numbers results in a positive number, and when you multiply a positive number by a negative number, the result is negative. Therefore, with an odd count of negative fractions, one negative will remain after all pairs are multiplied, resulting in a negative product.
No, you cannot use models to multiply fractions!!
When you divide by fractions, you invert and multiply.

multiply and divide fractions!-.-
Yes it is; note if you multiply numerator & denominator by 2 the fractions are the same.
No, you cannot use models to multiply fractions!!
same as you would multiply 2 normal fractions. Note: a negative times a negative = a positive so - a/b x - c/d = ac/bd e.g -1/2 x - 3/5 = 3/10
perpendicular fractions are gradients and are negative recipricals of each other and that multiply to give -1 for example:2/1 times -1/2 gives -1
You multiply the fractions
When you add or subtract fractions you cross multiply and when you multiply or divide fractions you across multiply.
Yes you do.
