Convert every ratio to a fraction a/b and identify the smallest decimal value. Since 1/3 is the only fraction less than 1, it is immediately the smallest.
Confusing the largest and smallest values, or assuming that the presence of 1 makes a ratio automatically the smallest without evaluating the denominator.
Convert ratios to fractions
Represent each ratio a:b as a fraction a/b.
1:1=1,2:1=2,1:3=31тАЛ,3:1=3
Compare values
Calculate the decimal value for each ratio. Comparing 1,2,0.33,3, we find that 0.33 is the smallest.

Identify the smallest
Since 0.33<1<2<3, the ratio 1:3 is the smallest.
1:3<1:1<2:1<3:1
B is correct because the ratio 1:3 represents the fraction 1/3, which is the smallest value among the given options.
This is a fundamental skill in data interpretation and probability, where comparing proportions is required to determine the likelihood of outcomes.
