Enter numbers into the table so that the paired values are in a proportional relationship.

Answer: y=6 for x=1 and x = 5 for y = 30.
Step-by-step explanation: We are given a table of x and y values:x :  1     3    ?      7      9y :  ?    18   30   72   54.The values of x and y are in proportion.Let us check the ratio of values of x to y.When x=3, we have y =18.Therefore x/y = 3/18 = 1/6.So, all values of x and y should be in ratio 1/6.In order words, the value of y's are 6 times the values of x's.So, for x=1, y= 6×1 = 6For y =30 , x= 30/6 = 5 Therefore, we need to fill y=6 for x=1 and value of x = 5 for y = 30.
