$3.5 - 2.75 + 5 frac{2}{5}$

Penyelesaian

$3.5 - 2.75 + 5 frac{2}{5} \ = frac{35}{10} - frac{275}{100} + frac{27}{5} \ = frac{(100 div 10) times 35}{100} - frac{275}{100} + frac{(100 div 5) times 27}{100} \ = frac{10 times 35}{100} - frac{275}{100} + frac{20 times 27}{100} \ = frac{350}{100} - frac{275}{100} + frac{540}{100} \ = frac{615}{100} = frac{123}{20} \ = 6 frac{3}{20}$
