1. ratio = 2 c of dressing / 4 lb of vegetables

Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.

Then d / v = 2/4 = 1/2 => d = v/2

Now you can make a table

v     d  

2    1

4    2

6    3

8    2

And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2

b) I already did it above as part ot the explanation: d/v = 1/2

(a) The model for the ratio of dressing and vegetables is the given by the equation  

[tex]\rm\bold{ V = 2D}[/tex]

A catering company’s recipe for salad uses a ratio of 2 c of dressing 4 lb of vegetables.

(a) We have to draw a model for the ratio.

(b) We have to write the ratio of dressing to vegetables as a reduced fraction.

Dressing = 2c

Vegetables = 4lb

The ratio of both is formulated as 2c : 4lb

(a)  Let us consider dressing is represented by D and amount of vegetables is represented by V then we can say that

[tex]\rm \dfrac{D}{V} = \dfrac{2}{4} = \dfrac{1}{2}[/tex]

hence when D increases by 1 unit variable V increases by two units and hence we can write

[tex]\rm V = 2D.....(1)[/tex]

The V and D values are shown in the table below

V    D

1     2

2    4

3    6

Equation (1) represents the model for the given situation.

(b) The ratio of dressing to vegetables as a reduced fraction is given by

[tex]\rm \dfrac{D}{V} = \dfrac{1}{2}[/tex]
