5/6x3/2-1 = 5/6-3/2-1 = 5/6+3/2-1 = tlong gan.. mksh klo no 1 isinya itu 28/18 ya atau brpa

[tex]\frac{5}{6}[/tex] x [tex]\frac{3}{2}[/tex] - 1 = ([tex]\frac{5}{6}[/tex] x [tex]\frac{3}{2}[/tex]) - 1 = [tex]\frac{5}{4}[/tex] - 1 = [tex]\frac{5}{4}[/tex] - [tex]\frac{4}{4}[/tex] = [tex]\frac{1}{4}[/tex]

[tex]\frac{5}{6}[/tex] - [tex]\frac{3}{2}[/tex] - 1 = [tex]\frac{5}{6}[/tex] - [tex]\frac{9}{6}[/tex] - [tex]\frac{6}{6}[/tex] = [tex]-\frac{10}{6}[/tex] = [tex]-\frac{5}{3}[/tex] = [tex]-1\frac{2}{6}[/tex]

[tex]\frac{5}{6}[/tex] + [tex]\frac{3}{2}[/tex] - 1 = [tex]\frac{5}{6}[/tex] + [tex]\frac{9}{6}[/tex] - [tex]\frac{6}{6}[/tex] = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex] = [tex]1\frac{1}{3}[/tex]
