9/10 + 1/5 – 1/2

= 9/10 + 2/10 – 5/10

= 11/10 – 5/10

= 6/10 = 3/5 (D) ✓

Jawaban:

$frac{9}{10} + frac{1}{5} - frac{1}{2} = frac{3}{5}$

$frac{9}{10} + frac{1}{5} - frac{1}{2} =$

$frac{9}{10} + frac{1}{5} = \ \ = frac{9}{10} + frac{2}{10} \ \ = frac{11}{10} \ \ = 1 frac{1}{10}$

$1 frac{1}{10} - frac{1}{2} = \ \ = frac{11}{10} - frac{1}{2} \ \ = frac{11}{10} - frac{5}{10} \ \ = frac{6}{10}$

$frac{6}{10} = frac{6 div 2}{10 div 2} = frac{3}{5}$

Jadi jawabannya D. ⅗
