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).
Converting decimals into fractions isn't hard. To convert a decimal into a fraction, you put the numbers to the right of the decimal point in the numerator (above the fraction line). Next, you place the number 1 in the denominator, and then add as many zeroes as the numerator has digits. Reduce the fraction if needed.
