Ratios are the same if both the numerator and denominator are multiplied or divided by the same number.
1/2 is the same as 5/10, since both were multiplied by 5 ((1*5)/(2*5))
Fractions (ratios) can be shown to be equivalent if the numerator and denominator can both be multiplied or divided by the same number to reach the reference ratio.
8/14 is equivalent to 4/7 since (8/2)/(14/2) = 4/7
