There are two equivalent ways
(I) Are the two ratios equivalent fractions?
If the ratios are a/b and c/d then can you find a number x such that
a = c*x and b = d*x.
so that a/b = c*x/d*x = c/d
This requires x = a/c = b/d
(II) Cross-multiply and equate.
If a/b = c/d then cross-multiplication gives ad = bc.
Also, if ad = bc then a/b = c/d (divide both sides by bd).

Is 3 over 4 a form proportion why?
A proportion is a statement that two ratios are equal.3/4 is one ratio, so it does not form a proportion.
