3.5 - 1 1/4 - 2/3 mohon jawabannya... terima kasih

[tex]3.5 - 1 \frac{1}{4} - \frac{2}{3} \\ = 3 + 0.5 - 1 - \frac{1}{4} - \frac{2}{3} \\ = 3 - 1 + ( \frac{1}{2} - \frac{1}{4} - \frac{2}{3} ) \\ = 2 + ( \frac{6 - 3 - 8}{12} ) \\ = 2 - \frac{5}{12} \\ = \frac{24 - 5}{12} \\ = \frac{19}{12} \\ = 1 \frac{7}{12} [/tex]

3,5=3 1/2

3 1/2-1 1/4=7/2-5/4=18/8=9/4=2 1/4
2 1/4-2/3=9/4-2/3=19/12=1 7/12
