Answer: the missing values are 7, 28 and 14
Step-by-step explanation:
In a proportional relationship, there is a constant relationship between the given variables. Thus, for any change in the value of one variable, there is a corresponding change in the value of the other variable.
The table shows a proportional relationship between values of servings
12 ,4 16 ,8
and values of ounces
21 ? ? ?
Let the missing values be x, y and z
Therefore,
21/12 = x/4
1.75 = x/4
x = 4 × 1.75
x = 7
21/12 = y/16
y = 16 × 1.75 = 28
21/12 = z/8
z = 1.75 × 8 = 14
