4 2/5: 1 3/4+3 2/5 kali 1 1/3= pake jalan plis

[tex] = 4 \frac{2}{5} \div 1 \frac{3}{4} + 3 \frac{2}{5} \times 1 \frac{1}{3} \\ = \frac{22}{5} \div \frac{7}{4} + \frac{17}{5} \times \frac{4}{3} \\ = ( \frac{22}{5} \times \frac{4}{7} ) + ( \frac{17}{5} \times \frac{4}{3} ) \\ = ( \frac{88}{35} ) + \frac{68}{15} \\ = \frac{264 + 476}{105} \\ = \frac{740}{105} \\ = \frac{148}{21} \\ = 7 \frac{1}{21} [/tex]
