Hello,
To convert 0.038¯146 into a fraction, we can use a relatively simple operation, which can be used for solving a variety of problems. We set x=0.038¯146, but we also see that mutitplying x by 1000 produces a similar repeating decimal, 1000x=38.¯146. We see that these repeating decimals, are both some relatively simple number + the repeating decimal 0.000146146.... To cancel out, we subtract x from 1000x, yielding 1000x−x=38.¯146−0.038¯146, so 999x=38.108, and after simplification, x=9527/249750
