Given the below mixed number;
![1(13)/(20)](https://img.qammunity.org/2023/formulas/mathematics/college/d8u3o6i9e7863rhvup9xlhjozq8ook36hk.png)
We can see from the above that we have 1 as the whole number component and 13/20 as the fractional component.
To convert the mixed number to a decimal, all we have to do is divide the fractional part and add the result to the whole number component as seen below;
![\begin{gathered} (13)/(20)=0.65 \\ 1+0.65=1.65 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/1hxxlcaxanzsnmmk4zfp2aicshbcgbhzin.png)
