We know that a real number is rational if and only if, when expressed as a decimal, it has a finite or recurring expansion. . . (put a point exactly over 8 and 2). For example, 5/4 = 1.25, 2/3 = 0.6, 20/7 = 2.857142857 or 20/7 = 2.857142
To convert 58 over 1,000,000 to a decimal, you simply divide the numerator (58) by the denominator (1,000,000). This results in 0.000058. This is because the decimal point is moved six places to the left to convert the fraction to a decimal.
Expressed as a decimal, 88/100000 = 0.00088
