However, if you're breastfeeding exclusively (and that means frequently, day and night), if your baby is younger than 6 months and if your period hasn't resumed, the so-called lactation amenorrhea method can be 98 percent effective in preventing pregnancy.
Then x has a expansion of decimal which terminates. 3) Let x =p/q be a rational number, such that the prime factorization of q is not of the form 25, where n, m are non-negative integers. Then, x has a expansion of decimal which is non-terminating repeating (recurring).

Decimal to fraction conversion is usually a two-step operation. 1  First, convert the decimal to fraction using tenths, hundredths, thousandths, etc. depending on the number of decimal places. 2  e.g. 1.75 = 1 75/100. 3  Next, simplify the fraction part to the lowest common term.
