Answer 1

Penyelesaian

[tex] \frac{22}{5} \div \frac{6}{10} \times \frac{23}{20} [/tex]

[tex] \frac{22}{5} \times \frac{10}{6} \times \frac{23}{20} [/tex]

[tex] \frac{44}{6} \times \frac{23}{20} [/tex]

[tex] \frac{22}{3} \times \frac{23}{20} [/tex]

[tex] \frac{506}{60} = \frac{253}{30} [/tex]

[tex] = 8 \frac{13}{30} [/tex]

Answer 2

[tex]4 \frac{2}{5} \div \frac{6}{10} \times 1 \frac{3}{20 } \\ = \frac{5 \times 4 + 2}{5} \times \frac{10}{6} \times \frac{20 \times 1 + 3}{20} \\ = \frac{22}{5} \times \frac{10}{6} \times \frac{23}{20} \\ = \frac{22 \times 10 \times 23}{5 \times 6 \times 20} \\ = \frac{5.060}{600} \\ = \bf8 \frac{13}{30} [/tex]
