Answer:
According to the local weather report, the probability of rain in Boston on February 24 is 0.13
Explanation:
% means "out of a hundred", so 50% is 50 out of a hundred, so 50/100, so 1/2 - a half.
That means, if we want to convert from a percentage to a decimal fraction, we just need to multiply the number before % by 1/100 (or divide by 100 I guess).
13% = 13*(1/100) = 13/100 = 0.13
