Kuis +50 poin [kexcvi]: ¼+½+¾+⅛+⅝=_____. ¼×½×¾×⅛×⅝=_____.

$1. : frac{1}{4} + frac{1}{2} + frac{3}{4} + frac{1}{8} + frac{5}{8} \ = frac{2 + 4 + 6 + 1 + 5}{8} \ = frac{18}{8} = 2 frac{2}{8} = 2 frac{1}{4}$

$2. : frac{1}{4} times frac{1}{2} times frac{3}{4} times frac{1}{8} times frac{5}{8} \ = frac{1 times 1 times 3 times 1 times 5}{4 times 2 times 4 times 8 times 8} \ = frac{15}{2.048}$

• Pertambahan

¼ + ½ + ¾ + ⅛ + ⅝ =…….

Samakan penyebut nya dengan KPK

$frac{2}{8} + frac{4}{8} + frac{6}{8} + frac{1}{8} + frac{5}{8} \ = frac{18}{8} \ = frac{9}{4} \ = 2 frac{1}{4}$

• Perkalian

$frac{1}{4} times frac{1}{2} times frac{3}{4} times frac{1}{8} times frac{5}{8} \ = frac{(3 times 5)}{(4 times 2 times 4 times 8 times 8)} \ = frac{15}{2048}$
