Jawaban:

= 2 frac{2}{3} - 2 frac{5}{12} + 2 frac{1}{4}

= frac{8}{3} - frac{29}{12} + frac{9}{4}

= frac{32 - 29 + 27}{12}

= frac{30}{12}

= frac{5}{2}

(C)

Jawaban:

2 frac{2}{3} - 2 frac{5}{12} + 2 frac{1}{4} \ (2 - 2 + 2) + ( frac{2}{3} - frac{5}{12} + frac{1}{4} ) \ 2( frac{8 - 5 - 3}{12} ) \ = 2( frac{6}{12} ) \ = 2 frac{1}{2} atau frac{5}{2}
