If each lower number, or denominator, is the same, you can order them like whole numbers, for instance 1/5, 3/5, and 8/5. Otherwise, you can alter your list of fractions to use the same denominator, without changing the size of any fraction.
Well, it is 9 months, but the average month is 4.3 weeks long, not 4. - (52 weeks / 12 months = 4.333 weeks per month.) - 4.333 weeks x 9 months = 38.99 weeks. So 9 months is just about the average of the 38 and 40 week numbers. To sum up, doctors talk about pregnancy on a 40 week timeline, the actual gestational time is about 38 weeks. All the being said, there are some variances in baby due date accuracy. Posted by Bill, almost a dad
Because not all pregnancies are equal in duration, it is impossible to predict the precise day on which your baby will be born. Pregnancies usually range from 37 weeks to 43 weeks, with most women giving birth between 39 weeks and 41 weeks after conception. Your due date is merely the middle of this fourteen-day window. There are several ways to calculate your due date.
