4 2/5rim + 4 /14 kodi + 2 1/3 lusin… Lembar

Dik :
* 1 rim = 500 lembar
* 1 kodi = 20 buah
* 1 lusin = 12 buah

maka :
4 frac{2}{5} : rim + 4 frac{1}{4} : kodi + 2 frac{1}{3} : lusin = ... \ = frac{22}{5} : rim + frac{17}{4} : kodi + frac{7}{3} : lusin \ = (frac{22}{5} times 500) + ( frac{17}{4} times 20) + ( frac{7}{3} times 12) \ = (200 + 85 + 28) : lembar \ = 313 : lembar

Penjelasan dengan langkah-langkah:

4 2/5 rim + 4 1/4 kodi + 2 1/3 lusin

(22/5 x 500) lembar + (9/4 x 20) lembar + (7/3 x 12) lembar

2200 lembar + 45 lembar + 28 lembar = 2273 lembar
