Is Ratio 1 : 1 = 1/2 (fraction)= 50% (percent)= 0.5 (decimal) or is Ratio 1 : 1 = 1/1(fraction) = 100% (percent) = 1.0 (decimal) which is correct?

Question

what is the 1 : 1 ratio mean? is it equal to 50% or 100%

Answer 1

To convert ratio 1:1 into fractions, we add 1+1=2, then. The fractions are 1/2 and 1/2. So 50%, 0.5 and 1/2 is the correct interpretation. The ratio of 1/2 to 1/2 is 1:1. In general, a:b means the fractions are a/(a+b) and b/(a+b).
