[tex]\frac{13}{10} =1.3.[/tex]
1. Write the mixed fraction.
[tex]1\frac{3}{10}[/tex]
2. Express the mixed fraction as an addition.
When converting a mixed fraction to addition, you want to write the proper fraction in the right ([tex]\frac{3}{10}[/tex]) and add a fraction with the numerator and denominator being the same number as the denominator in the proper fraction ([tex]\frac{10}{10}[/tex]) as many times as the number you have next to the proper fraction. For example, to convert this number to addition form we write:
[tex]\frac{3}{10} +\frac{10}{10}[/tex]
Notice that we only write [tex]\frac{10}{10}[/tex] once, because one os the number next to the proper fraction which it [tex]\frac{3}{10}[/tex].
3. Solve the addition of fractions.
[tex]\frac{3}{10} +\frac{10}{10}=\frac{3+10}{10} =\frac{13}{10}[/tex]
4. Express the final result.
[tex]\frac{13}{10} =1.3.[/tex]
