Jawaban:
Penyelesaian :[tex]\sf 1 \frac{4}{5} - (0.2 + \frac{3}{4} )[/tex]
[tex]\sf = \frac{9}{5} - ( \frac{2}{10} + \frac{3}{4} )[/tex]
[tex]\sf = \frac{9}{5} - ( \frac{1}{5} + \frac{3}{4} )[/tex]
[tex]\sf = \frac{9}{5} - ( \frac{4 \: + \: 15}{20} )[/tex]
[tex]\sf = \frac{9}{5} - \frac{19}{20} [/tex]
[tex]\sf = \frac{36 \: - \: 19}{20} [/tex]
[tex]\sf = \frac{17}{20} [/tex]
