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).
Convert Decimals to Fractions. 1  Step 1: Write down the decimal divided by 1, like this: decimal 1.  Step 2: Multiply both top and bottom by 10 for every number after the decimal point.
