Well, 6 of 8 is 3 of 4. So if there are 28 days, and 3 of 4 are cold, that's 21. So 21 is the best Answer.

Need gloves 6/8 days...75%

28 * 75% = 21

if it was cold enough SIX OF THE LAST EIGHTDAYS, it means 3/4 of the time, or 75 % of the time it MAY be cold enough in the future...BUT...what if there is a heat wave, or the last eight days were the first week of spring and the next (any number of) days were much warmer, or colder for that matter. Weather is UNPREDICTABLE, even by experts. The almanac maker may print the almanac, BUT: ONLY GOD MAKES THE WEATHER. Your question can be answered using 75 % of the number of days asked, but the chance of those answers being ACCURATE--who knows !!

you have 8 days for which 6 of were glove days.

take the total amount of days and divide by the total days in the sample.

28/8= 3.5

then multiply the total glove days in the sample by that answer

6*3.5=21

your anser is 21

in 8 days 6
in 1 day 6/8
in 28 days = 28 x 6/8 = 21

6/8 => 0.75

0.75 x 28 = 21

Therefore your answer is 21 days.
