Penjelasan dengan langkah-langkah:

frac{4}{5} + 3 frac{1}{4} - frac{1}{2}

= frac{4}{5} + frac{3 times 4 + 1}{4} - frac{1}{2}

= frac{4}{5} + frac{13}{4} - frac{1}{2}

= frac{4 times 8}{5 times 8} + frac{13 times 10}{4 times 10} - frac{1 times 20}{2 times 20}

= frac{32}{40} + frac{130}{40} - frac{20}{40}

= frac{32 + 130 - 20}{40}

= frac{210 - 20}{40}

= frac{190}{40}

= frac{190 div 10}{40 div 10}

= frac{19}{4}

= frac{16}{4} + frac{3}{4}

= frac{16 div 4}{4 div 4}

= frac{4}{1} + frac{3}{4}

= 4 + frac{3}{4}

= 4 frac{3}{4}
