What fraction is 8 min of 3 hr?
It is: 8/180 or 2/45 in its simplest form
Choose the ratio that you would use to convert 6.1 minutes to hours?
The trick to choosing the correct ratio for a conversion problem is to set it up so that the units that you do not want will get cancelled out, leaving the units that you do want. To do this, multiply by a fraction that has the units you want in the numerator and the units you want to get rid of in the denominator. Make sure that the numerator equals the denominator. If they are equal, the fraction is equal to one, and multiplying something by one does not change it. Since we're getting rid of minutes and looking for hours, we want to multiply by (1 hr / 60 min), which is the same as dividing by 60 minutes per hour (60 min/hr). 6.1 min ÷ 60 min/hr ≈ 0.102 hr
How much is 5 min of 1 hr?
5/60 = 1/12
How do you convert hours into a mixed number?
It may or may not be possible. The answer depends on how many hours and what units you are converting to. ===== If you are given a decimal amount of hours, just convert like any decimal. ex: 2.3 hours = 2 3/10 hours ex: 4.73 hours = 4 73/100 if the fractions will reduce you should do that also ex: 3.04 hours = 3 4/100 = 3 1/25 hours. If you are give hours and minutes, since there are 60 min in one hour, 60 becomes the denominator. Ex: 2 hr 17 min = 2 17/60 hr Ex: 3 hr 24 min = 3 24/60 = 3 2/5 hr (reduce using 12) If you have hours, minutes, and seconds ... again minutes as above. But there are 3600 seconds in an hour, so the denominator for seconds is 3600. Then add the two fractions using reducing and the lowest common denominator. Ex: 3 hr 15 min 20 sec = 3 and (15/60 + 20/3600) = 3 and (1/4 + 1/180) (LCD = 180) = 3 and (45/180 + 1/180) = 3 46/180 --- reduce = 3 23/90 hr
How do you express rate as a fraction?
Rate is the amount of something per unit time. Miles per hour and gallons per minute are examples of rates. Ten miles per hour, expressed as a fraction, is 10 mi/hr. Five meters per second: 5 m/s. Example Problem If you run a 26.2-mile marathon in four hours and 15 minutes, then your average rate was 26.2/4.25 = 6.16 mi/hr.
