use mulitplying by 1 to find an expression equivalent to (10/13) with a denominator of 39a
Thank you for your help.

ask yourself
"What did I multiply 13 by to get 39a ?"
How about 10/13 * 3a/(3a) = (30a)/(39a) 
Provide an example of at least five ordered pairs that do not model a function. The domain will be any five integers between 0 and 20. The range will be any five integers between 10 and 10. Your example must not be the same as those of other students or the textbook. Why does your example not model a function?
