Quarter to 10.
It is nothing. But a quarter past ten is a quarter hour after ten: that is 10:15 in the morning or evening.
a quarter past ten is 'dix heures et quart' in French.
You simply add "et quart" (pronounce [eh kar]) after the hour from which the quarter is past. "et quart" literally means "and a quarter".Hence "a quarter past ten" becomes "dix heures et quart" ("ten hours and a quarter")
A quarter past two!
quarter past ten means 15 minutes after 10o'clock
A quarter of ten, as it relates to time, is 9:45 A quarter of ten, as it relates to algebra, is 2.5
As there are 60 minutes in 1 hour, 9.75 must be 10.15 (quarter past ten).
It can't be half past and a quarter to 5 at the same time. I assume the answer is 5.30 for half past 5, and 4.45 for quarter to 5.
Ten past ten on a clock face has the hands balanced symmetrically on either side of the 12. Other times would also do this: quarter-past nine, for example, or twenty past eight. But ten ten looks best for display.
