3)
[tex] \frac{3}{4} - \frac{1}{5} - \frac{1}{2} [/tex]
[tex] \frac{?}{20} - \frac{?}{20} - \frac{?}{20} = \frac{?}{20} [/tex]
[tex] \frac{15}{20} - \frac{4}{20} - \frac{10}{20} = \frac{1}{20} [/tex]
4)
[tex] \frac{5}{6} - \frac{1}{3} - \frac{1}{4} [/tex]
[tex] \frac{?}{12} - \frac{?}{12} - \frac{?}{12} = \frac{?}{12} [/tex]
[tex] \frac{10}{12} - \frac{4}{12} - \frac{3}{12} = \frac{3}{12} = \frac{1}{4} [/tex]
5)
[tex] \frac{11}{12} - \frac{1}{3} - \frac{1}{6} [/tex]
[tex] \frac{?}{12} - \frac{?}{12} - \frac{?}{12} = \frac{?}{12} [/tex]
(tinggal dimasukin angkanya)

7)
[tex]3 \times \frac{3}{4} - \frac{2}{6} - \frac{1}{2} [/tex]
[tex] \frac{15}{4} - \frac{2}{6} - \frac{1}{2} [/tex]
[tex] \frac{?}{12} - \frac{?}{12} - \frac{?}{12} = \frac{?}{12} [/tex]
