1.2 5/6 - 1 2/3 + 4 7/9= 2.1 2/3 : 2 3/4 x 3 5/6= Maksud dari 2 5/6 dan yg sama kaya gitu maksud nya 2 ditengah 5 diatas 6 dibawah

1). [tex]2\frac{5}{6}[/tex] - [tex]1\frac{2}{3}[/tex] + [tex]4\frac{7}{9}[/tex] = [tex]\frac{17}{6}[/tex] - [tex]\frac{5}{3}[/tex] + [tex]\frac{43}{9}[/tex] = [tex]\frac{153}{54}[/tex] - [tex]\frac{90}{54}[/tex] + [tex]\frac{258}{54}[/tex] = [tex]\frac{321}{54}[/tex] = [tex]5\frac{51}{54}[/tex] = [tex]5\frac{17}{18}[/tex]

2). [tex]1\frac{2}{3}[/tex] : [tex]2\frac{3}{4}[/tex] x [tex]3\frac{5}{6}[/tex] = [tex]\frac{5}{3}[/tex] : [tex]\frac{11}{4}[/tex] x [tex]\frac{23}{6}[/tex] = [tex]\frac{5}{3}[/tex] x [tex]\frac{4}{11}[/tex] x [tex]\frac{23}{6}[/tex] = [tex]\frac{460}{198}[/tex] = [tex]2\frac{64}{198}[/tex] = [tex]2\frac{32}{99}[/tex]
