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
Pregnancy is considered late term from 41 weeks, 0 days' to 41 weeks, 6 days' gestation, and postterm at 42 weeks' gestation. Cochrane review showed that beginning sweeping at term (beyond 38 weeks) reduced the duration of pregnancy and reduced the likelihood that the pregnancy would continue beyond 41 weeks (relative risk = 0.59; 95% CI, 0.46 to 0.74) or 42 weeks (relative risk = 0.28; 95% CI, 0.15 to 0.50).
