Jawaban:
Operasi Hitung Pecahan
[tex] \frac{a}{b} \: \pm \: \frac{c}{d} = \frac{ad \: \pm \: bc }{bd} \\ [/tex]
[tex] \frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd} \\ [/tex]
[tex] \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} = \frac{ad}{bc} \\ [/tex]

Ditanyakan:
Hasil....?
Jawab:
[tex] = 2,375 + 1 \frac{3}{5} - 250\% \\ [/tex]
[tex] = \frac{2375}{1000} + \frac{8}{5} - \frac{250}{100} \\ [/tex]
[tex] = \frac{(2.375 + 1.600 -2.500) }{1.000} \\ [/tex]
[tex] = \frac{1.475}{1.000} \\ [/tex]
[tex] = 1,475[/tex]
Jadi, hasil dari [tex] 2,375 + 1 \frac{3}{5} - 250\% [/tex] adalah 1,475 (A).
