Are 7 9 and 70 90 are proportional?
In order to determine if two sets of numbers are proportional, you need to compare their ratios. For 7 and 9, the ratio is 7/9, which simplifies to 0.777. For 70 and 90, the ratio is 70/90, which simplifies to 0.778. Since these two ratios are not equal, 7 and 9 are not proportional to 70 and 90.

Is y equals 9 divided by x a proportional relationship?
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
What is the expression which connects y and x when y is inversely proportional to x and x equals 9 y equals 7. and what is the value of y when x equals 21?
x*y = k where k is a constant.When x = 9, y = 7 so k = 9*7 = 63 When x = 21, 21*y = 63 so y = 3.
