0.54 is a rational number = 54 / 100 = 2 * 27 / 2 * 50 = 27 / 50
But if 0.54 mean 0.5454545454 then:
100 * 0.5454545454 = 54.54545454
100 * 0.5454545454 - 0.5454545454 = 99 * 0.5454545454 =
54.54545454 - 0.54545454 = 54
99 * 0.5454545454 = 54 Divide both sides by 99
0.5454545454 = 54 / 99 = 6 * 9 / 11 * 9 = 6 / 11
But if 0.54 mean 0.5454545454 then:
100 * 0.5454545454 = 54.54545454
100 * 0.5454545454 - 0.5454545454 = 99 * 0.5454545454 =
54.54545454 - 0.54545454 = 54
99 * 0.5454545454 = 54 Divide both sides by 99
0.5454545454 = 54 / 99 = 6 * 9 / 11 * 9 = 6 / 11
