Answer:
John is not correct
Step-by-step explanation:
<em>(Unless you meant 5:6)</em>
Make the base question into 
simplify as much as possible. I found the Greatest Common Denominator (GCF) of<em> 35</em> and <em>42</em>, which was<em> 7</em>
divide <em>35</em> and <em>42</em> by the GCF<em> (7)</em>, and you should get 5:6 as your answer.

Answer:
Yes it is an equivalence relation
Explanation:
An equivalence relation is a binary relation between two values that are symmetric, transitive and reflexive. In other words, when we say a value x is equal(using "=") to a value y, there is an equivalence relation between them.
Example, given set {x, y, z} where ~ means equivalence:
x ~ y if y ~ z means symmetric
since x ~ y and y ~ z, then x ~ z means transitive
x ~ x means reflexive
Equivalence relations share a common attribute or attributes(example, a satisfying condition)
The above condition that two states are related from the set of all US states if they have a border in common satisfies the condition of equivalence listed hence it is an equivalence relation.
