1 hour and 45 minutes becomes 1.75 hours as a decimal.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 45 minutes, exactly as in the question. If you wanted it as a part of some other unit - for example, a day or year, it would have made sense to mention that. But since you did not, this is the best that I can do.
45 percent as a fraction is 45/100 or 9/20. 45 percent as a decimal is 0.45.
45/100 as a fraction in its simplest form = 9/20 45/100 as a decimal = 0.45
The answer depends on the units used for 45.
45 minutes is perfectly acceptable but you may prefer 45.0 minutes
It is: 45/60 = 0.75 of a hour
1 hour and 45 minutes becomes 1.75 hours as a decimal.
6.75 hours
0.75 of an hour.
8.75 hours
4.75 hours
7.75 hours =your question in decimal form.
1 hour = 60 minutes, so 45 minutes = 45/60 hour ⇒ 7 hours 45 minutes = 7 + 45/60 hours = 7 + 3x15/4x15 hours = 7 + (3 ÷ 4) hours = 7.75 hours
0.45 or 9/20
Expressed as a decimal fraction, 2 hours 45 minutes is equal to 2.75 hours.
