၂။ ၁ ႏွင့္ညီတယ္ (၃)
1/3 + 2/3 = 1, right?
1/3 = 0.33333...
2/3 = 0.66666...
0.33333... + 0.66666... = 1
Or, simplified: 0.99999... = 1
၃။ 64 (၂)
၁၃ ေကာင္ ေျမာက္ ကေန ၄၈ ေကာင္ေျမာက္ အထိက ၃၆ ေကာင္ရပါတယ္။
၃၆ ေကာင္က ဥၾကင္းမွာ၀တ္ရင္ ၆၄ ေကာင္က မ၀တ္ပါ။
၄။ ၃၆၅ ၁/၄ ထက္ နည္းပါတယ္ (၁)
ကမ ၻာ ဟာေန ကို တစ္ပတ္ပတ္မိရန္ ၃၆၅.၂၄၂၂ ရက္ အခ်ိန္ယူရပါတယ္
၅။ ၂၄ နာရီထက္နည္းပါတယ္ (၁)
A year equals 365.2422 days. If the earth wouldn't move around the sun, then the earth would make 365.2422 turns round her axis in one year. But because the earth also makes exactly one orbit around the sun in that year, the earth makes 365.2422 + 1 = 366.2422 turns round her axis in one year. One turn therefore takes
365.2422 × 24 hours / 366.2422 = 23 hours, 56 minutes and 4 seconds
၆။ Less than once in every four years (၃)
In our western calendar every year of which the number is divisible by 4 is a leap year, except century years not divisible by 400. For example, the years 1700, 1800 and 1900 were no leap years, but the year 2000 will be. Therefore not every fourth year is a leap year.
၇။ Gregorian calendar
In 45 B.C. Julius Caesar replaced the Roman calendar by the Julian calendar. In 1582 A.D. pope Gregory XIII replaced the Julian calendar by the Gregorian calendar, by improving the leap year rule. This Gregorian calendar is the calendar we still use today. The International calendar is one of the many proposals that have been done for the 'improvement' of the Gregorian calendar.
၈။ The summer on the northern hemisphere is longer than the summer on the southern hemisphere
The summer on the northern hemisphere, which lasts from the summer solstice (21 June) until the autumnal equinox (23 September), has an approximate length of 93.6 days. The winter on the northern hemisphere (and so the summer on the southern hemisphere), which lasts from the winter solstice (21 December) until the vernal equinox (21 March), has an approximate length of 89.0 days.
၉။ N has as many numbers as Z
Two sets A and B have the same number of elements if and only if there exists a so-called bijective function f from A to B.
Define the bijective function f: N -> Z as follows:
f(n) = -½n for n even
= ½(n + 1) for n odd
So for example, f(0) = 0, f(1) = 1, f(2) = -1, f(3) = 2, f(4) = -2, f(5) = 3 etcetera. f is a bijective function from N to Z, and therefore N and Z have the same number of elements.
Approximately 250 babies are born every minute worldwide (1996 estimate).
