8 hours/1 day * 7 days = 56 hours
Keep in mind that in this problem that the unit "days" is found on both the top (numerator) and also bottom (denominator). When multiplying, those devices cancel out, leaving the answer in hours. See exactly how this is a check on whether you put up the trouble right? If the systems don"t cancel, leaving you only through the correct ones, you did somepoint wrong. The rest is just math for the calculator, but setting up the problem ideal needs you to use your brain!
Now let"s take that very same instance and also reverse it. Imagine that you videotaped 56 hours of job-related, yet your employer requirements you to report the vacation time in days. With a convariation aspect, such as 8 hours = 1 work day, you have the right to arrange it via either value on height. How you perform it relies on what devices you desire to remain in your answer, and which systems you desire to cancel out. If you desire hours to cancel, leaving you a response in days, you put days on optimal and hrs on the bottom of the conversion variable.
1 day/8 hrs * 56 hours = 7 daysHere"s a daunting problem including unit conversion: Convertthe rate of light from meters per second to miles perhour. Given information: C=rate of light = 2.998 x 108 m/sec Given convariation factors: 100 cm = 1 m 60 sec = 1 min 2.54 cm = 1 inch 60 min = 1 hr 12 inches = 1 ft 5280 ft = 1 mile The trick to this difficulty is to break it down into simpler tomanage pieces, given that it actually entails two conversions (distancesystems and also time units).Tip 1: Convert time units from meters per second tometers per hour. Since there are 60 seconds per minute, and also 60minutes per hour, multiply meters per second by seconds per minuteand also minutes per hour to get your answer. Keep in mind that seconds andminutes cancel considering that they are in both the numerator and also thedenominator.(2.998 x 108 m/sec) x (60 sec/min) x (60 min/hr) =1.07928x1012m/hrTip 2: Convert Metric System units from meters tocentimeters making use of the provided convariation factor.

Why centimeters?Since you haven"t been given the conversion element to go directlyfrom meters to miles. You only know exactly how to transform meters tocentimeters, centimeters to inches, inches to feetand feet to miles.(1.07928 x 1012m/hr) x (100 cm/m) =1.07928x1014cm/hrStep 3: Convert English System units from inches to milesutilizing the provided indevelopment.(1.07928x1014cm/hr) x (1 in/2.54 cm) x (1 ft/12 in) x (1 mi/5280 ft) =670,633,500.4mi/hr
