any ratio that is of the form
1k              1            k          1
----    =  ------------ ------- =---------
7k              7            k          7


as k/k =1 
so if you find some ratio give to you such that u can factor our some number  k from both numerator and denominator and have 1/7 left out, then it is equivalent... for example
 
2      12    1      2         1
--- =-----=----- ------ =-----
14   72    7       2         7

Any ratio which can be simplified to 1/7 is equivalent to it. So, for example, if you multiply this fraction by 2, you get 2/14, which is equivalent. Or 3/21, or 4/28, or 5/35...
