Penjelasan dengan langkah-langkah:

13.

[tex]1\frac{1}{2} + 2\frac{2}{5} - \frac{20}{100} \\[/tex]

[tex]= \frac{3}{2} + \frac{12}{5} - \frac{2}{10}[/tex]

[tex]= \frac{15}{10} + \frac{24}{10} - \frac{2}{10}\\[/tex]

[tex]= \frac{37}{10}[/tex]

[tex]= 3\frac{7}{10}[/tex]

14.

[tex]= \frac{150}{1000} + \frac{7}{4} - \frac{50}{100}[/tex]

[tex]= \frac{15}{100} + \frac{175}{100} - \frac{50}{100}[/tex]

[tex]= \frac{140}{100}[/tex]

[tex]= 1\frac{2}{5}[/tex]

15.

[tex]= 3\frac{8}{10} + \frac{6}{8} - \frac{15}{100}[/tex]

[tex]= \frac{38}{10} + \frac{6}{8} - \frac{15}{100}[/tex]

= [tex]\frac{3040}{800} + \frac{600}{800} - \frac{120}{800}[/tex]

[tex]= \frac{3520}{800} = 4\frac{2}{5}[/tex]
