Is 0.8333333......a rational number?

YES!!! Because it can be converted to a RATIO. Hence Let 10P = 8.33333.... 100 P = 83.3333.... Subtract 90P = 75 P = 75/90 Cancel down by '5' P = 15/18 Cancel down by '3' P = 5/6 ( A RATIO). This is the fraction in its lowest terms. NB Irrational numbers are 'pi = 3.141592..... . Sqrt(2) = 1.414213562.... Casually irrational numbers have the decimals going to infinity, and there is no regular order in the decial digits. As the name suggests, irrational numbers cannot be converted to a ratio (fraction).

Why is a ratio expressed without writing units?

In a ratio of measurements for the same kinds of units, units get canceled. For example, in a ratio of 3 meters / 8 meters, you can cancel the "meters" in the numerator and the denominator. An important ratio is pi, which is the ratio of the circumference of a circle to its diameter. If you measure the circumference in feet, and the diameter in feet, then divide circumference/diameter, then the result is the dimensionless quantity 3.14159265.... If you go back and measure both in meters, you get the same answer.In a ratio of two measurements, the units cancel, so it makes no difference whether you write the units, or not.

You can't simplify that; 4 and 11 are relatively prime, i.e., they have no common factors which you might cancel.


Why do the fours in the numerator and denominator cancel out?
