1. [tex] \frac{3}{6} [/tex] x 0,6
= [tex] \frac{3}{6} [/tex] x [tex] \frac{6}{10} [/tex]
= [tex] \frac{18}{60} [/tex]
= [tex] \frac{3}{10} [/tex]
2. [tex] \frac{8}{12} [/tex] ÷ 0,3
= [tex] \frac{8}{12} [/tex] ÷ [tex] \frac{3}{10} [/tex]
= [tex] \frac{8}{12} [/tex] × [tex] \frac{10}{3} [/tex]
= [tex] \frac{80}{36} [/tex]
= 2[tex] \frac{8}{36} [/tex]
= 2[tex] \frac{2}{9} [/tex]
3. [tex] \frac{7}{8} [/tex] ÷ 5%
= [tex] \frac{7}{8} [/tex] ÷ [tex] \frac{5}{100} [/tex]
= [tex] \frac{7}{8} [/tex] × [tex] \frac{100}{5} [/tex]
= [tex] \frac{700}{40} [/tex]
= 17[tex] \frac{20}{40} [/tex]
= 17 [tex] \frac{1}{2} [/tex]
4. L persegi panjang
= p × l
= 2[tex] \frac{1}{2} [/tex] × 1[tex] \frac{3}{4} [/tex]
= [tex] \frac{5}{2} [/tex] × [tex] \frac{7}{4} [/tex]
= [tex] \frac{35}{8} [/tex]
= 4 [tex] \frac{3}{8} [/tex]
