Question

Tell whether the ratios form a proportion.

1/3 , 7/12

Answer 1

`(1)/(3) \\eq (7)/(12)`

Explanation:

Given the following ratios:


`(1)/(3) =(7)/(12)`

To tell whether or not two ratios can form a proportion it's asking if the two ratios are equivalent to each other. You can find this by multiplying the lower fraction by a common denominator to see if the lower fraction can equal the higher fraction.


`(1)/(3)`

`1*4=4`

`3*4=12`

`(1)/(3) \\eq (7)/(12)`

The ratios are not equivalent to each other which means they do not form a proportion.

Hope this helps.
