Fractions are ratios. Equivalent fractions form a proportion.
yes they can
The ratios a/b and c/d form a proportion is if their simplified forms are the same, or equivalently, if a*d = b*c
Yes
a/b = c/d if and only if a*d = b*c.
When two ratios form a proportion, the ratios are equal
Any two ratios, provided the second is not 0, form a proportion.

No, they do not.
Proportion
yes they can

A proportion is a statement that two ratios are equal.3/4 is one ratio, so it does not form a proportion.
what are 2 ways you can tell that 2 ratios from a propotion
When both can multiply its comparisons to when both ratios share the exact same numbers.
The fractions are proportional and their cross products are equal
Yes
