[tex] \frac{7}{5} \div \frac{3}{14} + (0.78 - 28\%)[/tex]
Ubah semua bilangan menjadi pecahan
[tex] \frac{7}{5} \div \frac{3}{14} + ( \frac{78}{100} + \frac{28}{100} ) \\ = \frac{7}{5} \div \frac{3}{14} + ( \frac{39}{50} + \frac{14}{50} ) \\ = \frac{7}{5} \times \frac{14}{3} + \frac{53}{50} \\ = \frac{98}{15} + \frac{53}{50} \\ = \frac{980}{150} + \frac{159}{150} \\ = \frac{1139}{150} [/tex]
