[tex]3 \frac{2}{3} + 2 \frac{1}{5} \times 50\% - 1.8[/tex]
Dijawab :
[tex] = \frac{9 + 2}{3} + \frac{2 \times 5 + 1}{5} \times ( \frac{50}{100} ) - 1.8[/tex]
[tex] = \frac{11}{3} + \frac{2 \times 5 + 1}{5} \times ( \frac{50}{100} ) - 1.8[/tex]
[tex] = \frac{11}{3} + \frac{10 + 1}{5} \times ( \frac{50}{100} ) - 1.8[/tex]
[tex] = \frac{11}{3} + \frac{11}{5} \times ( \frac{50}{100} ) - 1.8[/tex]
[tex] = \frac{11}{3} + \frac{11}{5} \times ( \frac{1}{2} ) - 1.8[/tex]
[tex] = \frac{11}{3} + \frac{11 \times 1}{5 \times 2} - 1.8[/tex]
[tex] = \frac{11}{3} + \frac{11}{10} - 1.8[/tex]
[tex] = \frac{110}{30} + \frac{33}{30} - 1.8[/tex]
[tex] = \frac{110 + 33}{30} - 1.8[/tex]
[tex] = \frac{143}{30} - 1.8[/tex]
[tex] = \frac{143}{30} - \frac{9}{5} [/tex]
[tex] = \frac{143}{30} - \frac{54}{30} [/tex]
[tex] = \frac{143 - 54}{30} [/tex]
[tex] = \frac{89}{30} [/tex]
[tex] = 2 \frac{29}{30} [/tex]
Jawaban:
[tex] \frac{89}{30} = 2 \frac{29}{30} [/tex]
