Question

Do the ratios 1/12 and 8/96 form a proportion? Explain.

Answer 1

The following is a type of proportion ==> a : b = c : d; and in this case we have: 
1 : 12 = 8 : 96 
It's not all that hard, all you need to know is the ''cross-multiplication'' methods for testing this kind of stuff. 

1 : 12 = 8 : 96 ? 
1 * 96 = 12 * 8 ? 
96 = 96 ? 
96 = 96 ==> CORRECT 

Answer 2

1/12 = 8/96
cross multiply
(1)(96) = (8)(12)
96 = 96

yes, this is a true proportion...keep in mind, proportions are nothing but equivalent fractions
