to change decimals to a fraction, we "add as many zeros at the bottom as there are decimals", in this case, there are two decimals, so we'll be using 00,
![\bf 13.\underline{67}\implies \cfrac{1367}{1\underline{00}}\implies 13(67)/(100)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/8uh4dt1inqeiaz42mha98s82kxwikgkz4c.png)
where do the 13 and 67 come from in the mixed fraction? well, 1367 ÷ 100 gives a quotient of 13, and a remainder of 67, and that's how the mixed fraction is structured.
