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
Weeks of pregnancy: It takes 266 days, or 38 weeks to bear a normal child from the date of conceiving to delivery. Since the majority of pregnant women is not aware of the date of impregnation, it is taken as the date of their last periods. This term lasts 280 days or 40 weeks. A pregnancy normally develops 38 weeks though gynecologists take it as 40-week period assuming that a pregnancy starts from the first day when their cycle began. The fetus is 2 weeks younger than the obstetricians believe. These 40 weeks are classified into 3 trimesters.
