1. 3/6 : 5/8 = 2. 15/20 :2/4 = 3. 7/8 : 12/30 = 4. 2/6 : 9/15 = 5. 7/8 : 4/12 = pakai caranya?????

[tex]1. = \frac{3}{6} \times \frac{8}{5} = \frac{24}{30} = \frac{4}{5 } [/tex]
[tex]2. = \frac{15}{20} \times \frac{4}{2} = \frac{120}{40} = 4[/tex]
[tex]5. = \frac{7}{8} \times \frac{12}{4} = \frac{84}{32} = \frac{21}{8} [/tex]
[tex]3. = \frac{7}{8} \times \frac{30}{12} = \frac{210}{96} = \frac{33}{16} [/tex]
[tex]4. = \frac{2}{6} \times \frac{15}{9} = \frac{30}{54} = \frac{5}{9} [/tex]
