14 11/18
I got this answer by doing 30 1/9 + 4 1/3= 34 4/9
Now I subtracted 34 4/9 by 19 5/6 to get the answer 14 11/18
TIP: When adding/subtracting/multiplying/dividing mixed numbers change them to an improper fraction first by multiplying the denominator and the whole number then adding the numerator
Answer:
My answers were (1,1) for both lmk if it works ;)
Step-by-step explanation:
i dont really know but im guessing use ratios. like 4:total volunteers
or something like that
|2x + y - 3z|
Plug in the values
|-4 + 10 - 9|
= |-3|
= 3
A rational number is a number that can be written in the form:

Where p and q are coprimes. We are asked for finite sets, we can rule out options 3 and 4. In the set in option 2 the first element is:

This number cannot be written a ratio. We can rule out option 2.
All the elements in the set from option 1 can be written in the form p/q.Thus, the answer is the first option.
