Answer:
If it is:
1,089-4,445= -3,356
but if it is the other way:
4,445-1,089= 3,356
Hope it helped!
First, we are going to want to see if there are any terms we can simplify. By examining the numerators and denominators of our functions, we can see that we can remove a 3 from the denominator of the second function and the numerator of the first function. This would be represented as:

Now, we can multiply the fractions. Remember that to multiply fractions, simply multiply both the numerators over both the denominators, as shown below:

By applying this information, we can solve for the product of the fractions:

Our answer is
.
The answer should be y= -1/4-2
That the variable Z is directly proportional to X and inversely proportional to Y means Z = A (X/Y)
=> A = Z* Y / X
=> 9.5 * 6 / 3 = Z * 12 /8
=> Z = 9.5 * 8 * 6 / (3 * 12) = 12.67
Answer: 12.67
