Is zero a rational number? Can you wriand q*0?1.te it in the form,where p and q are inmegers |
|
Answer» Rational number are the ones that can be expressed in the formp/qsuch thatp is an integerandq a non-zero integer. The definition does not say that this is the only form it can be expressed. Consider the following example: (√2)/(√2) = 1, which we know is a rational number. Here it is expressed as a ratio of two irrational numbers, but this does not make it an irrational number as it can also be expressed a ratio of two integers. The phrase “Any number which doesn't fulfill the above conditions is irrational”does NOTsay “Any number which can be written as a fractionp/q,where p and q are not integers, is irrational” Similarly, in the case of zero(0), it can be expressed in many ways with one of the cases being ratio of two integers (eg. 0/1 = 0/2 = … = 0) Thanks |

The average speed of a train is 20% less onthe return journey than on the onwardjourney. The train halts for half an hour atthe destination station before starting onthe return journey. If the total time takenfor the 'to and fro' journey is 23 h, coveringa distance of 1000 km, the speed of the trainon the return journey is |
|
Answer» Train was halted for half an hour.So, total time taken in Journey = 23 - (1/2) = 22.5 hours.Average speed in Whole Journey = 1000/22.5 = 44.5 km/hr.The average speed on return journey is 20% less than onward journey.Therefore, ratio of average speed of onward and return journey,= 100/80 = 5/4.Let average speed of onward journey = 5x.Average speed on return journey = 4x.Average speed on whole journey = (5x +4x)/244.5 = (5x + 4x)/289 = 9xx = 9.88.Average speed on return = 9.88 *4 = 39.52 = 40 kmph (Approx.) |
