Question

Find each ratio to y in decimal form. Then tell whether I and y are proportional. 3.08 1.4 y 7.04 3.2 3.08 1.4 15.62 = 7.04 3.2 7.1 15.62 7.1 O x and y are not proportional. O x and y are proportional.

Answer 1

In the given question the ratio of x to y is :

`(x)/(y)=(3.08)/(1.4)`

Divide 3.08/1.4

`(3.08)/(1.4)=2.2`

for the next :

`(7.04)/(3.2)=2.2`

for the next ratio:

`(15.62)/(7.1)=2.2`

Since all the ratio are equal to 2.2 So, x and y are proportion

Answer : Proportion
