Part A
Let
x-----> the weight of nuts in ounces
y -----> the weight of raisins in ounces
we have that
x/y=6/3
x/y=2
x=2y
that means----> the weight of nuts is two times the weight of raisins
Part 1
The ratio of ounces of nuts to ounces of raisins is 6 to 3
Part 2
In 4 batches of trail mix, the number of ounces of nuts is 24 oz and the number of ouns of raisins is 12 oz
Because
we have that
In one batch there is 6 oz of nuts and 3 ounces of raisins
so
In 4 batches ------> 4*6=24 oz of nuts
and
4*3=12 oz of raisins
Part 3
The ordered pair (18,9) means-----> 18 oz of nuts to 9 oz of raisins
Part B
we have that
Table A
ratio x/y is equal to
6/12=9/18=12/24=0.5 -----> equivalent ratios
Table B
ratio x/y
9/12=15/18 is not true
Table C
ratio x/y
9/6=12/9 is not true
Table D
ratio x/y
12/6=18/9=24/12=2 -----> equivalent ratios
therefore
the answer is table A and table D
