In the 24-hour time notation, the day begins at midnight, 00:00 or 0:00, and the last minute of the day begins at 23:59. Where convenient, the notation 24:00 may also be used to refer to midnight at the end of a given date [3]— that is, 24:00 of one day is the same time as 00:00 of the following day. Like other numbers, time can be added or subtracted. However, due to how time is defined, there exist differences in how calculations must be computed when compared to decimal numbers. The following table shows some common units of time. Unit Because slash is both sign for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3. Values are calculated for Length of engagement of 5xPitch. For calculations of different engagement length use the Thread Calculator'Adams, Anthony J.; Lovie-Kitchin, Jan (2004). "Ian L Bailey".

When using a LogMAR chart, visual acuity is scored with reference to the logarithm of the minimum angle of resolution, as the chart's name suggests. An observer who can resolve details as small as 1 minute of visual angle scores LogMAR 0, since the base-10 logarithm of 1 is 0; an observer who can resolve details as small as 2 minutes of visual angle (i.e., reduced acuity) scores LogMAR 0.3, since the base-10 logarithm of 2 is near-approximately 0.3; and so on.

Proper fraction button is used to change a number of the form of 9/5 to the form of 1 4/5. A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number). Now button will set the starting time to the current time. And the clear button resets the time inputs.Andy gets five out of 15 questions wrong in his math test. What fraction of the question does andy answer correctly?
