$a.bcdef...=\frac{a}{1}+\frac{b}{10}+\frac{c}{100}+\frac{d}{1000}+\frac{e}{10000}+\frac{f}{100000}...$

zzr0ck3r · Answer

example:

$1.34=1+\frac{3}{10}+\frac{4}{100}\=\frac{100}{100}+\frac{3*10}{100}+\frac{4}{100}=\frac{100+30+4}{100}\=\frac{134}{100}\=\frac{67}{50}$

`0.37` means `37 hundredths` since that 7 is in the hundredths place

so you write `37` over 100 to get $$\Large \frac{37}{100}$$

this means  $$\Large \frac{37}{100} = 0.37$$
