1 h = 0 d. 1 hour is 0 days.
Answer: 45 minutes in decimal is 0.75.
There are 60 minutes in 1 hour. To convert from minutes to hours, divide the number of minutes by 60. For example, 120 minutes equals 2 hours because 120/60=2.
1. Convert 45 minutes into hours. Therefore, 45 minutes = 45/60 hour = ¾ hour. 2.
For example 15 minutes (¼ hour) equals . 25, 30 minutes (½ hour) equals . 5, etc.
A time of day is written in the 24-hour notation in the form hh:mm (for example 01:23) or hh:mm:ss (for example, 01:23:45), where hh (00 to 23) is the number of full hours that have passed since midnight, mm (00 to 59) is the number of full minutes that have passed since the last full hour, and ss (00 to 59) is the ...
It is common to talk about 'half an hour' (30 minutes) and 'quarter of an hour' (15 minutes).
The Egyptians also divided the dark hours into 12 sections based on the appearance in the night sky of 12 stars as the night advanced. So with 12 hours of daylight and 12 of night, the 24 hour day was established.

(1 min = 60 seconds) Therefore 86,400 seconds in a day. So 1year=365 days have 86400365 seconds.
Answer: The time of 10 minutes written as a fraction of an hour in decimal form is equal to 0.167.
Who decided on these time divisions? THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
Historically, the word "minute" comes from the Latin pars minuta prima, meaning "first small part". This division of the hour can be further refined with a "second small part" (Latin: pars minuta secunda), and this is where the word "second" comes from.
And when the Great Depression hit in the 1930s, the U.S. Gov't saw Ford's shorter workweek as a way to fight the massive unemployment crisis – companies would need to hire more workers to get the job done.

An hour is a period of sixty minutes.
Half an hour means thirty minutes. It is half of an hour. An hour is a time period of sixty minutes.
In 24-hour (military) time, 12:00am is equal to 0000 and is read as “0 hundred hours”. 1:00am, or 0100, is pronounced as “zero 1 hundred hours”.
therefore 00.00 = midnight, or twelve o'clock at night.
