Math CentralQuandaries & Queries


Question from Jazzy, a teacher:

Twins are born once in every 89 births.
Identical twins are born 4 times in every 1000.
Triples are born once in every 6900 births.
write each frequency as a decimal and order the
decimals from least to greatest frequency.


Left handers are born 3 times in every 1500. Thus 3 in 1500 are left handers or the fraction of left handers is 3/1500 = 1/500.

Does this help?
